AssetBundles let you stream additional assets via the UnityWebRequest class and instantiate them at runtime. AssetBundles are created via BuildPipeline.BuildAssetBundle.
Note that bundles are not compatible between platforms. A bundle built for any of the standalone
platforms can only be loaded on that platform but not others.
Further example, a bundle built for iOS is not compatible with Android and vice versa. One difference
is shaders which are different between devices, as are textures.
