In the process of conforming to PEP 8

Put all imports on their own lines. Capitalized constant variables.
Fixed spacing and got all lines under 79/72 characters. Started making
non-public variables in classes and public functions to interact with
them. This still needs tons of work. Condensed the "move_or_interact"
function for better readability and less code overall. Fixed comment
spacing and format. Fixed multi-line dependency assignments.
