// RooCFunction2Binding is a templated implementation of class RooAbsReal that binds 
// generic C(++) functions to a RooAbsReal argument thus allowing generic C++
// functions to be used as RooFit functions. Instances of function binding
// classes are fully functional RooFit function objects with one exception:
// if the bound function is _not_ a standard TMath or MathMore function the
// class cannot be persisted in a RooWorkspace without registering the function
// pointer first using RooCFunction2Binding<T1,T2,T3>::register().
