* \defgroup tools_getset get_var and set_var macros
* \ingroup tools
*
* The macros in this group have the purpose to make writing \c get_<varname>() and \c set_<varname>(<varname>)
* methods for classes easier. They can be used by giving the type and the name of a private variable for which
* \c get_ and \c set_ methods should be created:
* \code
* class a {
* private:
* int var1;
* std::strign var2;
* public:
* GetSetMacro(int, var1);
* JKQTPGetMacro(std::string, var2);
* }
* \endcode
* This code will create a \c set_var1, a \c set_var2 and a \c get_var1 method with the apropriate types.
* All functions will be declared \c virtual and can thus be easily overloaded in inheriting classes. They are also
* declared \c inline so the compiler may optimize them by really inlining them.
*
* The GetSetMacro creates get and set methods while the GetMacro and the SetMacro only create one of the
* both.
