gale.factory module

This file contains the class Factory, holding a class (not an instance) and creating new instances of it at a given (x, y) position plus arbitrary extra constructor properties, and AbstractFactory, looking that class up by name within a given module so a Factory can be built from a string instead of importing the class directly.
