# status.py    Basic Status with battery voltage


#      import status provides printStatus(egpg,ds)

#      ./status.py    will print status once and exit
#
#      ./status.py -l (or -loop) will print status every 5 seconds
#
#      ./status.py -h (or --help) will print usage

#  Protected from No SPI Response Exceptions - continues
