[IDV #ORG-580351]: IDV - importing image-like data from Metop-A

Hi HP-

I guess we were really busy because this slipped through the cracks!

Projections will be problematic.  Currently, we only use lat/lon images.

At present we only handle point data as text, but are looking at 
ASCII grids as you see from the recent idvusers discussions.

If I put the following lines at the top of the file (removing the
first line already there):

(Longitude,Latitude) -> (radiance)
Longitude,Latitude,radiance

I can read the file in using the "I'm still feeling lucky" option
(which reads it as a VisAD adapter).  Then, I use the Any Field
formula to select a Color Shaded Display and select the field
for that data source.

We need to make adding the metadata interactive, but for now,try
editing the files and see how that works for you.
