The Formula Primitive class.
Helper class for TFormula to speed up TFormula evaluation TFormula can use all functions registered in the list of TFormulaPrimitives User can add new function to the list of primitives if FormulaPrimitive with given name is already defined new primitive is ignored
Example:
The following sufixes are currently used, to describe function arguments:
