[IDV #TNW-894406]: IDV: Lightning data

Dave, 

Please see the IDV screen casts located at

http://motherlode.ucar.edu/repository/entry/show/RAMADDA/Unidata/Staff/Julien+Chastang/Screen+cast?entryid=91013a46-c12c-4b1c-9f70-b646e27702be

called "Dave Light".

I bumble around a bit and also in the second lightning example, I should have 
chosen the "NAPLN" data source type, but hopefully this should be useful to 
you. Both movies are the same, but under different file formats.

Let us know what you think :-)

Thanks.

-Julien
