[Datastream #MJO-754339]: NLDN lightning data source

Hi Ryan, 

I did not see any dates/times associated with the files in question, maybe I 
missed that....not that critical :)

The NLDN data that flows via the LDM "lightning" feedtype is CG. This is likely 
to be different than data gathered from Vaisala, as they have and continue to 
improve their product and are incorporating IC/CC strokes currently.

Hope this helps, 

Jeff
