Hi folks,

  Let's follow the traditional style guide for Python, http://www.python.org/dev/peps/pep-0008/.

  I think we've been close to this historically, if there are places where the code is off we can fix
it over time.  Or, if there is a consistent deviation throughout the code we can document it and
retain the deviation.

  I'll be playing with pylint soon, I think it has an option for enforcing PEP 8.  We'll see what it says.

Best,

Trevor
