Generate DCM.PL commands from the output of a 'show ip route' to load into ONA

#
# Takes the output of a "show ip route" command from an IOS device
# and processes it. Simply get the output and save it to a file
# and then run this script against that file.
# 
# It will output dcm.pl command syntax to create a new subnet based
# on the route. The default subnet type will simply be 'LAN', please
# change that to an appropriate value if needed. Also the default
# subnet name will be 'SHOWROUTE-<IP>' to indicate it was created by
# this script. In all cases a new name should be determined.
#
# Another major point, not all routes equate to actual subnets. Some
# routes are summarized so that one route will include multiple
# subnets.  Be sure to examine these as it will cause overlaps while
# loading the data. I would suggest anything with a larger mask than
# /24 should be investigated.
#
# The major goal of this is to initially populate ONA with subnets
# that you can then load hosts and interfaces into.  It is step one
# in the process of adding data to ONA.
