/**
* Implements function call-backs.
*
* Functors may be defined for instance objects or classes.
*
* The method is created on first use, which allows the invokee (class or instance)
* to be omitted from the constructor.
*
* The class name takes precedence over the instance.
*
* If a functor is created with a particular instance, then that is used for all future calls;
* if an object is provided, it is ignored.
* This allows easy override of the table model behaviour.
*
* If an argument list is provided in the constructor, then that is ignored in subsequent invoke() calls.
*
* Usage:
* f = new Functor("methodName")
* o = f.invoke(object) - OR -
* o = f.invoke(object,params)
*
* f2 = new Functor(object,"methodName");
* o = f2.invoke() - OR -
* o = f2.invoke(params)
*
* f3 = new Functor(class,"methodName");
* o = f3.invoke(object) - will be ignored
* o = f3.invoke() - OR -
* o = f3.invoke(params)
* o = f3.invoke(object,params) - object will be ignored
