    PEP8 the codebase and add a test suite
    
    PEP8 is a widely used and accepted Python style. This commit fixes any
    PEP8 violations and adds a unit test that automatically lints new code
    for PEP8.
    
    There were several places where variables were being used that did not
    exist. In those cases I took a guess at what was intended.
