Added all the initial Affix files.
Deleted some files that are not needed.
Updated documentation for affixstackinterface.repy
Added more comments on affixstackinterface.repy
Modified affix_stack.repy and changed how the copy() method works. Now it uses the advertisement string to build a new AffixStack rather then using the stored AFFIX string.
* Changed the name of AffixStack.copy() to AffixStack.deepcopy().
* Changed the way deepcopy() works. Now the copy() method recursively
  goes through every AFFIX component in the stack and copies it over
  rather then creating a new stack using an AFFIX string.
AffixStack now adds RepyNetworkApiWrapper() at the bottom of the stack. Fixes #12.
Made some changes and confirmed that the core components can be used for basic
AFFIXs to write server/client application. Also added the file affixpythoninterface.py
to make it easier to use the AFFIX framework in Python.
Added some documentation in affixpythoninterface.py
Added the file affixpythoninterface.py which can be used to easily use the
AFFIX framework from python.
Moved where affixpythoninterface.py is located.
Added blank function definitions for some methods in affixpythoninterface.py
- Added all required repy files in repo.
- Added some documentation files under docs/ that show some use cases.
minor change to README
Updated use cases documentation.
Modified both affix_stack.repy and baseaffix.repy
Made the necessary changes to get the core AFFIX framework working. Also have made changes to compressionaffix and noopaffix.
Made many changes.
- Changed affix_stack to comply with the new design so it carries
  the root AFFIX component.
- Changed baseaffix so an AFFIX no longer refers to a stack. Instead
  an AFFIX just points to the next AFFIX in the stack.
- Added the functionalities pop(), peek() and push() into baseaffix
  so the AFFIXs themselves can modify the stack below them.
Changed the deepcopy() method in affix_stack.repy to address the issue of having an empty stack.
Commiting updated legacy affix and coordination affix.
