__init__ and render now take a generic bag of config properties, instead of a bunch of hard-coded ones.
Made required ini options clearly documented in constants.py. Code can depend on those being present.
Huge refactor of __main__ to use argparse, clearer code flow, smaller functions, etc.
Added /example dir as a basic template.
Removed run_planet.py as its not really needed, just pipeline stuff together.
