Possible Move and Refactor of generate.py

[jmwright]

See original comment here.

At some point we probably want to move the generate functionality into the nimble_orchestration module so we don't have do do weird path things. generate.py can then basically become a 2-3 line script.

This was in reference to the following line of code in nimble_server.py.

sys.path.append(os.path.dirname(__file__) + "/..")
