30	@file
31	@brief Definition of the Identifier class, definition and implementation of the ClassIdentifier class.
32
33	The Identifier contains all needed information about the class it belongs to:
34	- the name
35	- a list with all objects
36	- parents and children
37	- the factory (if available)
38	- the networkID that can be synchronised with the server
39	- all configurable variables (if available)
40
41	Every object has a pointer to the Identifier of its class. This allows the use isA(...),
42	isExactlyA(...), isChildOf(...) and isParentOf(...).
43
44	To create the class-hierarchy, the Identifier has some intern functions and variables.
45
46	Every Identifier is in fact a ClassIdentifier, but they are derived from Identifier.
