+/** \brief Encapsulation of prototypes for a numerical parser function.
+
+ Encapsulates the prototyp for numerical parser functions. The class
+ stores the number of arguments for parser functions as well
+ as additional flags indication the function is non optimizeable.
+ The pointer to the callback function pointer is stored as void*
+ and needs to be casted according to the argument count.
+ Negative argument counts indicate a parser function with a variable number
+ of arguments.
+ This class is not used for string function prototyping.
