Method or function calling interface.

Objects of this class contain the (CINT) environment to call a global function or a method for an object of a specific class with the desired arguments. This class is especially useful when a method has to be called more times for different objects and/or with different arguments. If a function or method needs to be called only once one better uses TInterpreter::Execute().
