\class RooCFunction4Binding
\ingroup Roofit

RooCFunction4Binding 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 RooCFunction4Binding<T1,T2,T3,T4>::register().
