Detailed Description

FactoryRegisterBase is the base class to all FactoryRegister's. A pointer to one of these is placed in the FactoryRegisterRegistry.

In general, a FactoryRegister must be a singleton. Unfortunately this will not happen in all circumstances, especially with dynamically linked libraries. The solution to this is to provide a single registry of registries.

This is a reference counted class because DLL's may be loaded and unloaded.
