csv for full history
Update for 19 (0x13) and 02 (0x02)

Could not find 19 (0x13) in the csv. But skipping over it for time delta appears to be correct.
Looks like 0x02 represents a weak signal (SensorWeakSignal)
file to find and print op_codes and their package contents.
did some tests to set time to decode the cgm
test to see how it saves changing multiple parts of the time.
Merge branch 'erobinson/cgm-decode' of http://github.com/erobinson/decoding-carelink into erobinson/cgm-decode
added tool to make it easier to decode mm .data files
testing out change for parsing months for timestamp
did some more work on the list_cgm.py script
updates to list_cgm.py to handle more commands

changing the parsing so that suggestion returns a partially filled
in record which then can be updated by parsing the data in the packet
minor update
minor updates
able to decode cgm pages pretty well now
able to sucessfully parse cgm data

there still may be some more data to parse for alarms and the like that are currently not in the data that was downloaded.
