// Define a file.
// This allows us to use dependency injection file-wide, instead of class/function wide.
// This brings some simplicity to each file, as each will have 
// a base, common framework.

  // As stated below, we want to listen on this error, otherwise the system will automatically 
  // trigger an error.
  this.on("error", function(error){

    throw Error(error);
  });
  // The dependency "router" can only be of type Ember.Oject.
  // This simulates types sorta in other languages (Java, PHP)
  // It does involve adding an extra step, instead of this feature being 
  // on the language level, but it'll work for now.
  // 
  // If lock returns false, it'll emit/trigger an error, unless you listen on the 
  // "error" event.

  // A service locator is an alternative to dependency injection, and is 
  // a lot simpler, though the syntax might be a little different.

  // Let's include another File module.
  // You NEED to know about the file you are using and what it expects.
  // otherwise, you'll set off some errors.
  // You simply call the function and pass parameters as an array.
  // This will run the async method.
