/**
* Phaser has one single cache in which it stores all assets.
*
* The cache is split up into sections, such as images, sounds, video, json, etc. All assets are stored using
* a unique string-based key as their identifier. Assets stored in different areas of the cache can have the
* same key, for example 'playerWalking' could be used as the key for both a sprite sheet and an audio file,
* because they are unique data types.
*
* The cache is automatically populated by the Phaser.Loader. When you use the loader to pull in external assets
* such as images they are automatically placed into their respective cache. Most common Game Objects, such as
* Sprites and Videos automatically query the cache to extract the assets they need on instantiation.
*
* You can access the cache from within a State via `this.cache`. From here you can call any public method it has,
* including adding new entries to it, deleting them or querying them.
*
* Understand that almost without exception when you get an item from the cache it will return a reference to the
* item stored in the cache, not a copy of it. Therefore if you retrieve an item and then modify it, the original
* object in the cache will also be updated, even if you don't put it back into the cache again.
*
* By default when you change State the cache is _not_ cleared, although there is an option to clear it should
* your game require it. In a typical game set-up the cache is populated once after the main game has loaded and
* then used as an asset store.
*
