start.py

DESCRIPTION:
  This script should be used to invoke the game. It allows optional
  arguments to be passed to it that can override the settings in config.py
  if desired.
  
USAGE:
  To invoke the game with an option defined below, for example -w and
  --debug, use `python start.py -w --debug'

  To define a new option:
    1) Create a new constant in constants.py. Best practice is to 
       incrememnt the value by 1 for each new flag. 
       Example: (in constants.py) NEW_FLAG = 4
    2) Ensure this file imports the new flag
    3) In this file, add one or more argv mappings to optionsMap
       Example: optionsMap = { ..., '-n' : NEW_FLAG, '--new' : NEW_FLAG }
    4) If thew new option can override a setting found in config.py,
       it must do it prior to main being imported near the end of this file.
