But this is only initializing a GRASS session, without any mechanism to
terminate a session. Basic usage in the documentation:

        # ... use GRASS modules here
        # remove the session's gisrc file to end the session
        os.remove(gisrc)

maybe a new fn to terminate a session is needed? This fn could clean temp
files like clean_temp() in grass.py and also clean any default sqlite db
when terminating the grass session.
