Nebula3's runtime type information for one class. Every class derived

from Core::RefCounted should use the macros __DeclareClass and __ImplementClass
|
|
to properly initialize the runtime type information for the class. This
|
|
will also automatically register the class with the Core::Factory object
|
|
to implement object construction from class name string or fourcc code.
