Switch.py is now [PEP 8](http://www.python.org/dev/peps/pep-0008/) compliant. Integrated PEP 8 and PyLint checking into Geany, learning a lot now.
Switch.py now fully conforms to PEP 8, at least Geany tells me it "compiles" without errors.
CamReader.py cleaned up a bit (preparing for `pep8`), introduced new directories for the snapshot and trigger option, and re-written both those cases to (hopefully) be clearer to follow.
Removed `tree` from README, since that didn't show well on GitHub
`pep8`ifyied CamReader.py (except line length)
some more output to Switch.py
