/**
    @file
    @brief Definition of the Identifier class, definition and implementation of the ClassIdentifier class.

    The Identifier contains all needed information about the class it belongs to:
     - the name
     - a list with all objects
     - parents and children
     - the factory (if available)
     - the networkID that can be synchronised with the server
     - all configurable variables (if available)

    Every object has a pointer to the Identifier of its class. This allows the use isA(...),
    isExactlyA(...), isChildOf(...) and isParentOf(...).

    To create the class-hierarchy, the Identifier has some intern functions and variables.

    Every Identifier is in fact a ClassIdentifier, but they are derived from Identifier.
