@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.
