You can overide or subclass methods. However...

Overide happens at the local stack level - you copy the library's method 
and overide it from the 
local stack's methods. 

Subclassing is a bit different:
You have a mehod called CreateClient that creates clients. If you wanted 
to use that to createClient
objects or Companies, you copy the method, rename it and change what you 


if you have a generic createobject method, you can improve this one by 
providing what kind of
object you want to create. The createObject is then scripted to either do 
different things per object
(which will overbloat the function) or you create a subtype creation 
branching for the different objects
that createobject can make. Harder to explain given the number of
