[Xastir] ShapeFile Zone duplicates?

[Lynn W. Deffenbaugh (Mr)]

As many of you know, I've been working on Shapefile support in 
APRSISCE/32 and have recently uncovered an unexpected "feature" in one 
of the NWS shapefiles, specifically c_15jl09.shp.  It seems that this 
shapefile has multiple objects for a single zone ID and even better, a 
few of those multiple objects are actually the responsibility of 
different CWAs (namely FLC087 and VAC099).

I was wondering how xastir handles this when attempting to light up an 
area for an NWS message-specified zone?  Currently I just run with the 
first one, but am considering actually merging the multiple definitions 
into one and activating the composite results.  I've not yet actually 
written code to actually SEE the areas to know if they're different and 
if so how.
