I think the file creation using an appropriate maxtimes, or maxstns
should keep the header size down. So, I will probably set a default
maxgrids in dcgrib as 2000 or 5000.

I think a good hour in the summer can still exceed 30,000 lightning strikes.
I'd like to get away from special ltgmap and ltglist versions of the surface
programs. Maybe 1/2 hourly lightning files. The problem with too many files
is slowing down the Garp and NMAP searches. Fewer files is better. Do you have
any feeling for the maximum number of flashes we should store in a single file?
