 * @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.
