  This code registers an injection for Ember.Application.

  If an Ember.js developer defines a subclass of DS.Store on their application,

  each have the store made available to them.

  For example, imagine an Ember.js application with the following classes:

  an inverse. For example, imagine the following models are

  the has-many.

/**

*/

/**
  A transaction allows you to collect multiple records into a unit of work
  that can be committed or rolled back as a group.

  For example, if a record has local modifications that have not yet
  been saved, calling `commit()` on its transaction will cause those
  modifications to be sent to the adapter to be saved. Calling
  `rollback()` on its transaction would cause all of the modifications to
  be discarded and the record to return to the last known state before
  changes were made.

  If a newly created record's transaction is rolled back, it will
  immediately transition to the deleted state.

  If you do not explicitly create a transaction, a record is assigned to
  an implicit transaction called the default transaction. In these cases,
  you can treat your application's instance of `DS.Store` as a transaction
  and call the `commit()` and `rollback()` methods on the store itself.

  Once a record has been successfully committed or rolled back, it will
  be moved back to the implicit transaction. Because it will now be in
  a clean state, it can be moved to a new transaction if you wish.

  ### Creating a Transaction

  To create a new transaction, call the `transaction()` method of your
  application's `DS.Store` instance:

      var transaction = App.store.transaction();

  This will return a new instance of `DS.Transaction` with no records
  yet assigned to it.

  ### Adding Existing Records

  Add records to a transaction using the `add()` method:

      record = App.store.find(App.Person, 1);
      transaction.add(record);

  Note that only records whose `isDirty` flag is `false` may be added
  to a transaction. Once modifications to a record have been made
  (its `isDirty` flag is `true`), it is not longer able to be added to
  a transaction.

  ### Creating New Records

  Because newly created records are dirty from the time they are created,
  and because dirty records can not be added to a transaction, you must
  use the `createRecord()` method to assign new records to a transaction.

  For example, instead of this:

    var transaction = store.transaction();
    var person = App.Person.createRecord({ name: "Steve" });

    // won't work because person is dirty
    transaction.add(person);

  Call `createRecord()` on the transaction directly:

    var transaction = store.transaction();
    transaction.createRecord(App.Person, { name: "Steve" });

  ### Asynchronous Commits

  Typically, all of the records in a transaction will be committed
  together. However, new records that have a dependency on other new
  records need to wait for their parent record to be saved and assigned an
  ID. In that case, the child record will continue to live in the
  transaction until its parent is saved, at which time the transaction will
  attempt to commit again.

  For this reason, you should not re-use transactions once you have committed
  them. Always make a new transaction and move the desired records to it before
  calling commit.

/**
  The Mappable mixin is designed for classes that would like to
  behave as a map for configuration purposes.

  For example, the DS.Adapter class can behave like a map, with
  more semantic API, via the `map` API:

    DS.Adapter.map('App.Person', { firstName: { key: 'FIRST' } });

  Class configuration via a map-like API has a few common requirements
  that differentiate it from the standard Ember.Map implementation.

  First, values often are provided as strings that should be normalized
  into classes the first time the configuration options are used.

  Second, the values configured on parent classes should also be taken
  into account.

  Finally, setting the value of a key sometimes should merge with the
  previous value, rather than replacing it.

  This mixin provides a instance method, `createInstanceMapFor`, that
  will reify all of the configuration options set on an instance's
  constructor and provide it for the instance to use.

  Classes can implement certain hooks that allow them to customize
  the requirements listed above:

  * `resolveMapConflict` - called when a value is set for an existing
    value
  * `transformMapKey` - allows a key name (for example, a global path
    to a class) to be normalized
  * `transformMapValue` - allows a value (for example, a class that
    should be instantiated) to be normalized

  Classes that implement this mixin should also implement a class
  method built using the `generateMapFunctionFor` method:

    DS.Adapter.reopenClass({
      map: DS.Mappable.generateMapFunctionFor('attributes', function(key, newValue, map) {
        var existingValue = map.get(key);

        for (var prop in newValue) {
          if (!newValue.hasOwnProperty(prop)) { continue; }
          existingValue[prop] = newValue[prop];
        }
      })
    });

  The function passed to `generateMapFunctionFor` is invoked every time a
  new value is added to the map.

/**
  The store contains all of the data for records loaded from the server.
  It is also responsible for creating instances of DS.Model that wrap
  the individual data for a record, so that they can be bound to in your
  Handlebars templates.

  Define your application's store like this:

       MyApp.Store = DS.Store.extend();

  Most Ember.js applications will only have a single `DS.Store` that is
  automatically created by their `Ember.Application`.

  You can retrieve models from the store in several ways. To retrieve a record
  for a specific id, use `DS.Model`'s `find()` method:

       var person = App.Person.find(123);

  If your application has multiple `DS.Store` instances (an unusual case), you can
  specify which store should be used:

      var person = store.find(App.Person, 123);

  In general, you should retrieve models using the methods on `DS.Model`; you should
  rarely need to interact with the store directly.

  By default, the store will talk to your backend using a standard REST mechanism.
  You can customize how the store talks to your backend by specifying a custom adapter:

       MyApp.store = DS.Store.create({
         adapter: 'MyApp.CustomAdapter'
       });

  You can learn more about writing a custom adapter by reading the `DS.Adapter`
  documentation.

        App.Person.find(1);

    If the record with that `id` had not previously been loaded, the store will
    return an empty record immediately and ask the adapter to find the data by
    calling the adapter's `find` method.

    The `find` method will always return the same object for a given type and
    `id`. To check whether the adapter has populated a record, you can check
    its `isLoaded` property.

    ---

    To find all records for a type, call `find` with no additional parameters:

        store.find(App.Person);
        App.Person.find();

    This will return a `RecordArray` representing all known records for the
    given type and kick off a request to the adapter's `findAll` method to load
    any additional records for the type.

    The `RecordArray` returned by `find()` is live. If any more records for the
    type are added at a later time through any mechanism, it will automatically
    update to reflect the change.

    ---

    To find a record by a query, call `find` with a hash as the second
    parameter:

        store.find(App.Person, { page: 1 });
        App.Person.find({ page: 1 });

    This will return a `RecordArray` immediately, but it will always be an
    empty `RecordArray` at first. It will call the adapter's `findQuery`
    method, which will populate the `RecordArray` once the server has returned
    results.

    You can check whether a query results `RecordArray` has loaded by checking
    its `isLoaded` property.

  /**
    This allows an adapter to acknowledge that it has saved all
    necessary aspects of a relationship change.

    This is separated from acknowledging the record itself
    (via `didSaveRecord`) because a relationship change can
    involve as many as three separate records. Records should
    only move out of the in-flight state once the server has
    acknowledged all of their relationships, and this differs
    based upon the adapter's semantics.

    There are three basic scenarios by which an adapter can
    save a relationship.

    ### Foreign Key

    An adapter can save all relationship changes by updating
    a foreign key on the child record. If it does this, it
    should acknowledge the changes when the child record is
    saved.

        record.eachRelationship(function(name, meta) {
          if (meta.kind === 'belongsTo') {
            store.didUpdateRelationship(record, name);
          }
        });

        store.didSaveRecord(record, data);

    ### Embedded in Parent

    An adapter can save one-to-many relationships by embedding
    IDs (or records) in the parent object. In this case, the
    relationship is not considered acknowledged until both the
    old parent and new parent have acknowledged the change.

    In this case, the adapter should keep track of the old
    parent and new parent, and acknowledge the relationship
    change once both have acknowledged. If one of the two
    sides does not exist (e.g. the new parent does not exist
    because of nulling out the belongs-to relationship),
    the adapter should acknowledge the relationship once
    the other side has acknowledged.

    ### Separate Entity

    An adapter can save relationships as separate entities
    on the server. In this case, they should acknowledge
    the relationship as saved once the server has
    acknowledged the entity.

  WARNING: Much of these docs are inaccurate as of bf8497.

  This file encapsulates the various states that a record can transition
  through during its lifecycle.

  ### State Manager

  A record's state manager explicitly tracks what state a record is in
  at any given time. For instance, if a record is newly created and has
  not yet been sent to the adapter to be saved, it would be in the
  `created.uncommitted` state.  If a record has had local modifications
  made to it that are in the process of being saved, the record would be
  in the `updated.inFlight` state. (These state paths will be explained
  in more detail below.)

  Events are sent by the record or its store to the record's state manager.
  How the state manager reacts to these events is dependent on which state
  it is in. In some states, certain events will be invalid and will cause
  an exception to be raised.

  States are hierarchical. For example, a record can be in the
  `deleted.start` state, then transition into the `deleted.inFlight` state.
  If a child state does not implement an event handler, the state manager
  will attempt to invoke the event on all parent states until the root state is
  reached. The state hierarchy of a record is described in terms of a path
  string. You can determine a record's current state by getting its manager's
  current state path:

      record.get('stateManager.currentPath');
      //=> "created.uncommitted"

  The `DS.Model` states are themselves stateless. What we mean is that,
  though each instance of a record also has a unique instance of a
  `DS.StateManager`, the hierarchical states that each of *those* points
  to is a shared data structure. For performance reasons, instead of each
  record getting its own copy of the hierarchy of states, each state
  manager points to this global, immutable shared instance. How does a
  state know which record it should be acting on?  We pass a reference to
  the current state manager as the first parameter to every method invoked
  on a state.

  The state manager passed as the first parameter is where you should stash
  state about the record if needed; you should never store data on the state
  object itself. If you need access to the record being acted on, you can
  retrieve the state manager's `record` property. For example, if you had
  an event handler `myEvent`:

      myEvent: function(manager) {
        var record = manager.get('record');
        record.doSomething();
      }

  For more information about state managers in general, see the Ember.js
  documentation on `Ember.StateManager`.

  ### Events, Flags, and Transitions

  A state may implement zero or more events, flags, or transitions.

  #### Events

  Events are named functions that are invoked when sent to a record. The
  state manager will first look for a method with the given name on the
  current state. If no method is found, it will search the current state's
  parent, and then its grandparent, and so on until reaching the top of
  the hierarchy. If the root is reached without an event handler being found,
  an exception will be raised. This can be very helpful when debugging new
  features.

  Here's an example implementation of a state with a `myEvent` event handler:

      aState: DS.State.create({
        myEvent: function(manager, param) {
          console.log("Received myEvent with "+param);
        }
      })

  To trigger this event:

      record.send('myEvent', 'foo');
      //=> "Received myEvent with foo"

  Note that an optional parameter can be sent to a record's `send()` method,
  which will be passed as the second parameter to the event handler.

  Events should transition to a different state if appropriate. This can be
  done by calling the state manager's `transitionTo()` method with a path to the
  desired state. The state manager will attempt to resolve the state path
  relative to the current state. If no state is found at that path, it will
  attempt to resolve it relative to the current state's parent, and then its
  parent, and so on until the root is reached. For example, imagine a hierarchy
  like this:

      * created
        * start <-- currentState
        * inFlight
      * updated
        * inFlight

  If we are currently in the `start` state, calling
  `transitionTo('inFlight')` would transition to the `created.inFlight` state,
  while calling `transitionTo('updated.inFlight')` would transition to
  the `updated.inFlight` state.

  Remember that *only events* should ever cause a state transition. You should
  never call `transitionTo()` from outside a state's event handler. If you are
  tempted to do so, create a new event and send that to the state manager.

  #### Flags

  Flags are Boolean values that can be used to introspect a record's current
  state in a more user-friendly way than examining its state path. For example,
  instead of doing this:

      var statePath = record.get('stateManager.currentPath');
      if (statePath === 'created.inFlight') {
        doSomething();
      }

  You can say:

      if (record.get('isNew') && record.get('isSaving')) {
        doSomething();
      }

  If your state does not set a value for a given flag, the value will
  be inherited from its parent (or the first place in the state hierarchy
  where it is defined).

  The current set of flags are defined below. If you want to add a new flag,
  in addition to the area below, you will also need to declare it in the
  `DS.Model` class.

  #### Transitions

  Transitions are like event handlers but are called automatically upon
  entering or exiting a state. To implement a transition, just call a method
  either `enter` or `exit`:

      myState: DS.State.create({
        // Gets called automatically when entering
        // this state.
        enter: function(manager) {
          console.log("Entered myState");
        }
      })

// Implementation notes:
//
// Each state has a boolean value for all of the following flags:
//
// * isLoaded: The record has a populated `data` property. When a
//   record is loaded via `store.find`, `isLoaded` is false
//   until the adapter sets it. When a record is created locally,
//   its `isLoaded` property is always true.
// * isDirty: The record has local changes that have not yet been
//   saved by the adapter. This includes records that have been
//   created (but not yet saved) or deleted.
// * isSaving: The record's transaction has been committed, but
//   the adapter has not yet acknowledged that the changes have
//   been persisted to the backend.
// * isDeleted: The record was marked for deletion. When `isDeleted`
//   is true and `isDirty` is true, the record is deleted locally
//   but the deletion was not yet persisted. When `isSaving` is
//   true, the change is in-flight. When both `isDirty` and
//   `isSaving` are false, the change has persisted.
// * isError: The adapter reported that it was unable to save
//   local changes to the backend. This may also result in the
//   record having its `isValid` property become false if the
//   adapter reported that server-side validations failed.
// * isNew: The record was created on the client and the adapter
//   did not yet report that it was successfully saved.
// * isValid: No client-side validations have failed and the
//   adapter did not report any server-side validation failures.

// The dirty state is a abstract state whose functionality is
// shared between the `created` and `updated` states.
//
// The deleted state shares the `isDirty` flag with the
// subclasses of `DirtyState`, but with a very different
// implementation.
//
// Dirty states have three child states:
//
// `uncommitted`: the store has not yet handed off the record
//   to be saved.
// `inFlight`: the store has handed off the record to be saved,
//   but the adapter has not yet acknowledged success.
// `invalid`: the record has invalid information and cannot be
//   send to the adapter yet.

/**
  A serializer is responsible for serializing and deserializing a group of
  records.

  `DS.Serializer` is an abstract base class designed to help you build a
  serializer that can read to and write from any serialized form.  While most
  applications will use `DS.JSONSerializer`, which reads and writes JSON, the
  serializer architecture allows your adapter to transmit things like XML,
  strings, or custom binary data.

  Typically, your application's `DS.Adapter` is responsible for both creating a
  serializer as well as calling the appropriate methods when it needs to
  materialize data or serialize a record.

  The serializer API is designed as a series of layered hooks that you can
  override to customize any of the individual steps of serialization and
  deserialization.

  The hooks are organized by the three responsibilities of the serializer:

  1. Determining naming conventions
  2. Serializing records into a serialized form
  3. Deserializing records from a serialized form

  Because Ember Data lazily materializes records, the deserialization
  step, and therefore the hooks you implement, are split into two phases:

  1. Extraction, where the serialized forms for multiple records are
     extracted from a single payload. The IDs of each record are also
     extracted for indexing.
  2. Materialization, where a newly-created record has its attributes
     and relationships initialized based on the serialized form loaded
     by the adapter.

  Additionally, a serializer can convert values from their JavaScript
  versions into their serialized versions via a declarative API.

  ## Naming Conventions

  One of the most common uses of the serializer is to map attribute names
  from the serialized form to your `DS.Model`. For example, in your model,
  you may have an attribute called `firstName`:

  ```javascript
  App.Person = DS.Model.extend({
    firstName: DS.attr('string')
  });
  ```

  However, because the web API your adapter is communicating with is
  legacy, it calls this attribute `FIRST_NAME`.

  You can determine the attribute name used in the serialized form
  by implementing `keyForAttributeName`:

  ```javascript
  keyForAttributeName: function(type, name) {
    return name.underscore.toUpperCase();
  }
  ```

  If your attribute names are not predictable, you can re-map them
  one-by-one using the adapter's `map` API:

  ```javascript
  App.Adapter.map('App.Person', {
    firstName: { key: '*API_USER_FIRST_NAME*' }
  });
  ```

  This API will also work for relationships and primary keys. For
  example:

  ```javascript
  App.Adapter.map('App.Person', {
    primaryKey: '_id'
  });
  ```

  ## Serialization

  During the serialization process, a record or records are converted
  from Ember.js objects into their serialized form.

  These methods are designed in layers, like a delicious 7-layer
  cake (but with fewer layers).

  The main entry point for serialization is the `serialize`
  method, which takes the record and options.

  The `serialize` method is responsible for:

  * turning the record's attributes (`DS.attr`) into
    attributes on the JSON object.
  * optionally adding the record's ID onto the hash
  * adding relationships (`DS.hasMany` and `DS.belongsTo`)
    to the JSON object.

  Depending on the backend, the serializer can choose
  whether to include the `hasMany` or `belongsTo`
  relationships on the JSON hash.

  For very custom serialization, you can implement your
  own `serialize` method. In general, however, you will want
  to override the hooks described below.

  ### Adding the ID

  The default `serialize` will optionally call your serializer's
  `addId` method with the JSON hash it is creating, the
  record's type, and the record's ID. The `serialize` method
  will not call `addId` if the record's ID is undefined.

  Your adapter must specifically request ID inclusion by
  passing `{ includeId: true }` as an option to `serialize`.

  NOTE: You may not want to include the ID when updating an
  existing record, because your server will likely disallow
  changing an ID after it is created, and the PUT request
  itself will include the record's identification.

  By default, `addId` will:

  1. Get the primary key name for the record by calling
     the serializer's `primaryKey` with the record's type.
     Unless you override the `primaryKey` method, this
     will be `'id'`.
  2. Assign the record's ID to the primary key in the
     JSON hash being built.

  If your backend expects a JSON object with the primary
  key at the root, you can just override the `primaryKey`
  method on your serializer subclass.

  Otherwise, you can override the `addId` method for
  more specialized handling.

  ### Adding Attributes

  By default, the serializer's `serialize` method will call
  `addAttributes` with the JSON object it is creating
  and the record to serialize.

  The `addAttributes` method will then call `addAttribute`
  in turn, with the JSON object, the record to serialize,
  the attribute's name and its type.

  Finally, the `addAttribute` method will serialize the
  attribute:

  1. It will call `keyForAttributeName` to determine
     the key to use in the JSON hash.
  2. It will get the value from the record.
  3. It will call `serializeValue` with the attribute's
     value and attribute type to convert it into a
     JSON-compatible value. For example, it will convert a
     Date into a String.

  If your backend expects a JSON object with attributes as
  keys at the root, you can just override the `serializeValue`
  and `keyForAttributeName` methods in your serializer
  subclass and let the base class do the heavy lifting.

  If you need something more specialized, you can probably
  override `addAttribute` and let the default `addAttributes`
  handle the nitty gritty.

  ### Adding Relationships

  By default, `serialize` will call your serializer's
  `addRelationships` method with the JSON object that is
  being built and the record being serialized. The default
  implementation of this method is to loop over all of the
  relationships defined on your record type and:

  * If the relationship is a `DS.hasMany` relationship,
    call `addHasMany` with the JSON object, the record
    and a description of the relationship.
  * If the relationship is a `DS.belongsTo` relationship,
    call `addBelongsTo` with the JSON object, the record
    and a description of the relationship.

  The relationship description has the following keys:

  * `type`: the class of the associated information (the
    first parameter to `DS.hasMany` or `DS.belongsTo`)
  * `kind`: either `hasMany` or `belongsTo`

  The relationship description may get additional
  information in the future if more capabilities or
  relationship types are added. However, it will
  remain backwards-compatible, so the mere existence
  of new features should not break existing adapters.

      into a key in the adapter-provided data hash. For example,
      if the model's attribute name was `firstName`, and the
      server used underscored names, you would return `first_name`.
    * `primaryKey`: returns the key that should be used to
      extract the id from the adapter-provided data hash. It is
      also used when serializing a record.
  */

  /**
    A hook you can use in your serializer subclass to customize
    how an unmapped attribute name is converted into a key.

    By default, this method returns the `name` parameter.

    For example, if the attribute names in your JSON are underscored,
    you will want to convert them into JavaScript conventional
    camelcase:

    ```javascript
    App.MySerializer = DS.Serializer.extend({
      // ...

      keyForAttributeName: function(type, name) {
        return name.camelize();
      }
    });
    ```

    @method keyForAttributeName
    @param {DS.Model subclass} type the type of the record with
      the attribute name `name`
    @param {String} name the attribute name to convert into a key

    @returns {String} the key
  */
  keyForAttributeName: function(type, name) {
    return name;
  },

  /**
    A hook you can use in your serializer to specify a conventional
    primary key.

    By default, this method will return the string `id`.

    In general, you should not override this hook to specify a special
    primary key for an individual type; use `configure` instead.

    For example, if your primary key is always `__id__`:

    ```javascript
    App.MySerializer = DS.Serializer.extend({
      // ...
      primaryKey: function(type) {
        return '__id__';
      }
    });
    ```

    In another example, if the primary key always includes the
    underscored version of the type before the string `id`:

    ```javascript
    App.MySerializer = DS.Serializer.extend({
      // ...
      primaryKey: function(type) {
        // If the type is `BlogPost`, this will return
        // `blog_post_id`.
        var typeString = type.toString().split(".")[1].underscore();
        return typeString + "_id";
      }
    });
    ```

    @method primaryKey

  An adapter is an object that receives requests from a store and
  translates them into the appropriate action to take against your
  persistence layer. The persistence layer is usually an HTTP API, but may
  be anything, such as the browser's local storage.

  ### Creating an Adapter

  First, create a new subclass of `DS.Adapter`:

      App.MyAdapter = DS.Adapter.extend({
        // ...your code here
      });

  To tell your store which adapter to use, set its `adapter` property:

      App.store = DS.Store.create({
        adapter: App.MyAdapter.create()
      });

  `DS.Adapter` is an abstract base class that you should override in your
  application to customize it for your backend. The minimum set of methods
  that you should implement is:

    * `find()`
    * `createRecord()`
    * `updateRecord()`
    * `deleteRecord()`

  To improve the network performance of your application, you can optimize
  your adapter by overriding these lower-level methods:

    * `findMany()`
    * `createRecords()`
    * `updateRecords()`
    * `deleteRecords()`
    * `commit()`

  For an example implementation, see `DS.RestAdapter`, the
  included REST adapter.

  /**
    Loads a payload for a record into the store.

    This method asks the serializer to break the payload into
    constituent parts, and then loads them into the store. For example,
    if you have a payload that contains embedded records, they will be
    extracted by the serializer and loaded into the store.

    For example:

        adapter.load(store, App.Person, {
          id: 123,
          firstName: "Yehuda",
          lastName: "Katz",

          }]
        });

    the embedded `App.Occupation` with ID `345`.

/**
  The REST adapter allows your store to communicate with an HTTP server by
  transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
  should use the REST adapter.

  This adapter is designed around the idea that the JSON exchanged with
  the server should be conventional.

  ## JSON Structure

  The REST adapter expects the JSON returned from your server to follow
  these conventions.

  ### Object Root

  The JSON payload should be an object that contains the record inside a
  root property. For example, in response to a `GET` request for
  `/posts/1`, the JSON should look like this:

  ```js
  {
    "post": {
      title: "I'm Running to Reform the W3C's Tag",
      author: "Yehuda Katz"
    }
  }
  ```

  ### Conventional Names

  Attribute names in your JSON payload should be the underscored versions of
  the attributes in your Ember.js models.

  For example, if you have a `Person` model:

  ```js
  App.Person = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    occupation: DS.attr('string')
  });
  ```

  The JSON returned should look like this:

  ```js
  {
    "person": {
      "first_name": "Barack",
      "last_name": "Obama",
      "occupation": "President"
    }
  }
  ```

  ## Customization

  ### Endpoint path customization

  Endpoint paths can be prefixed with a `namespace` by setting the namespace
  property on the adapter:

  ```js
  DS.RESTAdapter.reopen({
    namespace: 'api/1'
  });
  ```
  Requests for `App.Person` would now target `/api/1/people/1`.

  ### Host customization

  An adapter can target other hosts by setting the `url` property.

  ```js
  DS.RESTAdapter.reopen({
    url: 'https://api.example.com'
  });
  ```

  ### Headers customization

  Some APIs require HTTP headers, eg to provide an API key. An array of
  headers can be added to the adapter which are passed with every request:

  ```js
  DS.RESTAdapter.reopen({
    headers: {
      "API_KEY": "secret key",
      "ANOTHER_HEADER": "asdsada"
    }
  });
  ```
