	<brief_description>
		Base class for reference-counted objects.
	</brief_description>
	<description>
		Base class for any object that keeps a reference count. [Resource] and many other helper objects inherit this class.
		Unlike [Object]s, References keep an internal reference counter so that they are automatically released when no longer in use, and only then. References therefore do not need to be freed manually with [method Object.free].
		In the vast majority of use cases, instantiating and using [Reference]-derived types is all you need to do. The methods provided in this class are only for advanced users, and can cause issues if misused.
