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.
