Template definition for classes that help resetting an object's value.
A stack allocated object of this type autonomically resets the value of an at construction time passed object to null when it reaches the end of its scope.
Intended usage:
int theObject = 0; { Steinberg::FNuller<int> theNuller (theObject); theObject = 1; } // Here the destructor of theNuller resets the value of theObject to 0.
