     95/**
     96    @brief Declares an XML attribute with a name, which will be set through a variable and gotten from a function.
     97    @param classname The name of the class owning this param
     98    @param paramname The name of the attribute
     99    @param variable Name of the variable used to save the value
     100    @param savefunction A function to get the value of the param from the object (~a get-function)
     101    @param xmlelement The XMLElement, you get this from the XMLPort function
     102    @param mode The mode (load or save), you get this from the XMLPort function
     103
     104    In the XML file, a param or attribute will be set like this:
     105    <classname paramname="value" />
     106
     107    The macro will then store "value" in the variable or read it when saving.
