[EAS] USVI and PR: polygons versus political boundaries

[Sean Donelan]

Trying to draw polygons between the U.S. Virgin Islands and the British 
Virgin Islands can create some very oddball warning boundaries. 
Sometimes its clearer to just reference the political subdivisions.

I have no idea what WEA cell towers would be included or excluded from 
this warning polygon versus just referencing Culebra (72049) and Vieques 
(72147).

Sometimes polygons work best. Sometimes civil identifies work best. Being 
able to use more than one geo-location system allows different choices for 
different situations.
