Give access to entries by index or key. Can be used instead of a linked list.\n\n```\nStability: 4 - API Frozen\n```\n( see [Stability Index](http://nodejs.org/api/documentation.html#documentation_stability_index) ) \n\n## Install\n\nas node module with npm:\n```bash\nnpm install indexed-map --production\n```\n\n## Usage\n\nCan be used as node module 'indexed-map', as AMD module 'indexed-map' or as global class at `window.IndexedMap`.\n\n```js\nvar IndexedMap = require('indexed-map');\nvar myMap = IndexedMap();\n// add an entry at the end\nmyMap.insert('myKey', { myProperty:'My Value' });\n```\n\nKeys have to be of type 'string' and unique in map.\nValues can by any type, there is no restrictions.\n\nSome methods supported in two versions, one with key as reference and the\nother works with index as reference (has suffix 'At').\n\n### Constructor\n\n* `var myMap = IndexedMap();`\n* `var myMap = new IndexedMap();`\n\nKeyword `new` is optional, it will be called by IndexedMap itself, if necessary.\n\n### properties\n\n* `length` {number} the count of entries\n\n* `keys` {Array} keys in the current order\n\n	It is the real keys array of the indexedMap, not a clone. So do not\n	add, change or remove elements. That would result in an inconsistent state of indexedMap itself.\n\n	The advantage of not cloning the key map is, that you can easily manipulate the order of keys, if you like.\n	So you could use the reverse or sort method of Array.\n\n### has, get, insert, set, move, remove\n\n* `has( key:string ):boolean`\n\n	checks, if given key is in map.\n\n	*return* {boolean} true, if it could found otherwise false\n\n* `get( key:string ) : value|null`\n* `getAt( index:number ) : value|null`\n \n	*return* Value for given key/index or null, if key was not found.\n\n* `getFirst():value|null`\n* `getLast():value|null`\n\n	*return* Value of first/last entry or null, if map is empty.\n\n* `insert( key:string, value:any ):value|null`\n* `insertAt( index:number, value:any ):value|null`\n\n	Insert new element before the referenced element targetKey.\n	If reference is null or not found, new element is inserted at the end\n	of the list.\n	\n	*return* Value for key or null if !key or key always used.\n\n\n* `set( key:string, value:any ) : oldValue|null`\n* `setAt( index:number, value:any ) : oldValue|null`\n	\n	Overwrite the value for the given key/index.\n	\n	*return* The old value or null, if key/index not found.\n\n* `move( key:string, targetKey:string ) : value|null`\n* `moveAt( index:number, targetIndex:number ) : value|null`\n	\n	Move the key to position of targetKey by inserting key before targetKey.\n	If targetKey is not found, key will be moved to the end.\n	\n	*return* Value for key or null if key was not found.\n\n* `remove( key:string ) : oldValue|null`\n* `removeAt( index:number ) : oldValue|null`\n	\n	Remove the entry for the given key.\n	\n	*return* The old value or null, if key was not found.\n\n### next, previous\n\nThe IndexedMap do not have a current element. To get next or previous entry,\nyou need to give a reference entry to the function.\n\n* `nextKeyOf( key:string ) : key|null`\n* `prevKeyOf( key:string ) : key|null`\n\n	*return* key from entry next/previous to given key or null, if key\n	has no next/previous.\n\n* `getNextOf( key:string ) : value|null`\n* `getPrevOf( key:string ) : value|null`\n	\n	*return* Value from entry next/previous to given key or null, if key\n	has no next/previous.\n\n\n### iterating methods\n\n* `sort( [callback] )`\n	\n	Sort the map, that method manipulate the indexedMap.\n	This function is analog to the sort function of Array.\n	if no callback is specified, keys will be sorted lexicographically\n	\n	*params* callback {function(this:IndexedMap, valueA:any, valueB:any):number} - optional\n	- called in context of indexedMap\n	- compareFunction have to return _0_ for equal, _<0_ for a < b or _>0_ for a > b\n	\n	*return* The indexedMap\n\n* `find(callback [, startIndex])`\n	\n	Returns the first key, where callback function returns true.\n\n	*param* {function(this:IndexedMap, key:string, value:any):boolean} callback - required\n	- called for every entry in context of indexedMap\n	- return true will stop the search and return the value of current visited entry.\n	\n	*param* {number} startIndex - optional\n	Position to start the search, default is 0.\n	\n	*return* Value of first entry found or null, if nothing found\n\n* `each(callback [, startIndex])`\n\n	Iterate over the indexedMap. Start at given startIndex. Run until end\n	or the given callback returns 'false'.\n\n	*param* {function(this:IndexedMap, key:string, value:any):boolean} callback - required\n	- called for every entry in context of current IndexedMap\n	- stop loop from within the callback function by returning false\n	\n	*param* {number} startIndex - optional\n	  position to start the run, default: 0\n	\n	*return* Zhe indexedMap or null for error (missing callback).\n\n\n## Test\n\n```bash\ncd <IndexedMapDir>\nnpm install .\nnpm test\n```\n\n## License\n\nThe MIT License\n\nCopyright (c) 2012-2013 Tobias Lindig\n\nPermission is
