# This is a script to claim a device into Dashboard, create a network for it and bind 
#  the network to a pre-existing template.
#
# You need to have Python 3 and the Requests module installed. You
#  can download the module here: https://github.com/kennethreitz/requests
#  or install it using pip.
#
# To run the script, enter:
#  python deployappliance.py -k <key> -o <org> -s <sn> -n <netw> -c <cfg_tmpl> [-t <tags>] [-a <addr>] [-m ignore_error]
#
# To make script chaining easier, all lines containing informational messages to the user
#  start with the character @
