 Adding a member function to a C++ class does not require recompilation
of other source files which access the class unless the size of the
class has changed (i.e. you added members). Also, unless you need to
access the private parts of a class there is no real reason to actually
modify the class definition itself. (Perhaps) the easiest thing to do
is to make a derived (sub) class of the base (super) class which contains
the method you want to add. Note that following this scheme could get
quite messy since you could end up with a bunch of class hierarchy trees.
