[Support #ZDT-182699]: PV in IDV

Hi Jim-

I found one error which was that absolute vorticity was being calculated 
incorrectly.  That will be fixed in the nightly build.  However, I'm now trying 
to get IPV correct. I compared the results from GEMPAK and they match.  

However, IPV is even worse now. :-( I'll have to do some plan view plots in 
GEMPAK to compare with since I don't have any other program to show what the 
isosurface should look like.

Thanks for your patience.
