I hate bash, replaced with python

Next commit will have the bash script removed

+# NAME: 	check_snmp_usage.py
+#
+# COMMENT:  Nagios check to monitor Internet connections that have monthly 
+#           usage caps. Requires the creation of a state file. No warning or
+#           critical thresholds necessary, will go WARNING if you are headed
+#           towards over usage based upon current usage and current date. Will
+#           go CRITICAL when you've actually surpassed your allotment. Will use
+#           command line SNMP so no extra Python libraries are required.
+#
+# TODO:     - Everything
+#           - As an added feature I'll someday make it work on daily caps and
+#           additionally make it so you can adjust the day of the month to reset
+#           - Add in the ability to use perfdata as a simple bandwidth
+#           method to create graphs in Nagios
+#           - SNMP v3?
