Minor changes to get 'make test' to pass.
- some namespace conflicts due to unpep8- fixed infinite recursion caused by removing redundant makeIntfPair
First crack at restoring mininet python style, assisted by handy'unpep8' script, which does most of the work.
- topo.py is still in pep8- not all examples work, but this is due to other issues
Renamed mn_run.py -> mn, mn_clean.py -> mnclean; updated Makefle
It's possible that mn_clean is a bit easier to read; mnclean may be easierto type, however.
Added variables to Makefile so that source files are listed in a singlelocation.
Add static code checking for style and errors
This required a change to logging, which now uses a singleton pattern.
For all future checkins, 'make codecheck' should pass.
Add example unit tests and Makefile target
Add make clean to remove dist files created by setuptools
