36    @ingroup Class Super
37    @brief Definition of all super-function related macros, used to call functions of the base class.
38
39    This file defines all macros needed to add a new "super-function". If you add
40    a super-function, you can call <tt>SUPER(myclass, functionname, arguments)</tt>
41    inside your code and the function of the parent-class gets called. This is comparable
42    to <tt>super.functionname(arguments)</tt> in Java or other languages.
43
44    This works only with virtual functions that return nothing (@c void) and belong to
45    classes that have an @ref orxonox::Identifier "Identifier". Arguments however are
46    supported, there's no limitation for their number and type, except that the type has
47    to be known in Super.h.
48
49    To add a new super-function, you have to process 4 steps:
50
51    -# Add a new @c SUPER macro <br />
52       This allows you to call the super-function in your code. <br />
53       Location: This file (Super.h), marked with "--> HERE <--" comments (1/3)
54    -# Call the @c SUPER_FUNCTION_GLOBAL_DECLARATION_PART1/2 macros. <br />
55       This defines some global classes and templates, needed to create and call the super-functions. <br />
56       Location: This file (Super.h), marked with "--> HERE <--" comments (2/3)
57    -# Call the @c SUPER_INTRUSIVE_DECLARATION macro. <br />
58       This will be included into the declaration of @c ClassIdentifier<T>. <br />
59       Location: This file (Super.h), marked with "--> HERE <--" comments (3/3)
60    -# Call the @c SUPER_FUNCTION macro. <br />
61       This defines a partially specialized template that will decide if a class is "super" to another class.
62       If the check returns true, a @c SuperFunctionCaller gets created, which will be used by the @c SUPER macro.
63       You have to add this into the header-file of the baseclass of the super-function (the class that first
64       implements the function), below the class declaration. You can't call it directly in this file, because
65       otherwise you had to include the headerfile right here, which would cause some ugly back-dependencies,
66       include loops and slower compilation. <br />
67       Dont forget to include Super.h in the header-file. <br />
68       Location: The header-file of the baseclass (Baseclass.h), below the class declaration
