Modified Files:
	pylib/TW: Components.py

Log Message:
Removed remaining references to concept of "overlaying" things.  Added
'IPostProcessor' and 'SimplePostProcessor', which will allow things like
registries of classes to be built.  Example use::

class MyClass:

   a = 1

   b = 'two'

   def myRegistry(parents):
       # do stuff here to alter parents' output

   myRegistry = SimplePostProcessor(myRegistry)

The 'myRegistry' function will be called after all non-postprocessor
features have been finished - so it can look over the results and do
something with/to them, such as registering them in a special attribute.
