[netCDFJava #CZW-502913]: combining satellite bands via ncml

Hi Joleen,

I noticed in your aggregation that you are "cheating" the wavebands into 
pressure levels, presumably because the CDM stack does not currently 
recognize wavebands.  I don't know if this leads to some sort of 
unexpected problem.  I'll let you know what I figure out.

Also, I asked another member of the IDV team about the middle mouse 
button function.  So far, all I've gotten is head-scratching.  My best 
guess at this point is that the middle mouse button feature you've 
mentioned might be a hardware artifact.  Not all mice have three buttons 
(or even two, for that matter), so it could be that your middle mouse 
button maps to a convenient function, but I don't think we could 
guarantee this across all platforms.

Cheers,
   Lansing
