Reogranizing the contents of gameobjs.py into the sgrid package; breaking out gameobj, player, item, and location modules.  Removing the unnecessary .pyc file and __pycache__ directory contents.
Adding a .gitignore file to avoid accidentally committing unwanted files to the repo (__pycache__ directories and .pyc files).
Switching to use of super() to reference inhreited __init__() methods in the Item, Location, and Player classes.
Making the 'quit' command return a code to the main sgrid.py script to keep flow-of-control centralized to the run_game() function.
