'''
This is a blank application template to build on top of hblink.py. It contains
only the things you need to, essentially, run hblink.py underneath and do nothing
else. The expected behaviour is to override the dmrd_received function from
hblink.py to do somethign meaningful, so that framework is completed, but as
it stands, still does nothing with the DMRD packet.
