Removed underscores for public Node methods. Minor cleanup & comments.
Add new loglevel to display CLI output only
Also print warning if user chooses a loglevel that will hide CLI output.
Added convenience mode to allow info( 'a', 1, 'b' )
Later we may wish to optimize this so that the arg lists arenot created if the logging level is too low.
Added debug() convenience function.
Added warn to complement info, error.
Added info() and error() as aliases for lg.info() and lg.error()
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 logging_mod.py -> log.py
Updated other files accordingly.
