		@remarks
			Why do we do this? Well, it's because the Singleton implementation is in a .h file,
			which means it gets compiled into anybody who includes it. This is needed for the Singleton
			template to work, but we actually only want it compiled into the implementation of the
			class based on the Singleton, not all of them. If we don't change this, we get link errors
			when trying to use the Singleton-based class from an outside dll.
		@par
			This method just delegates to the template version anyway, but the implementation stays in this
			single compilation unit, preventing link errors.
