[Proj] MGRS/USNG support?

Such as it may be for the United States, a minor glitch won't necessarily
mean the difference between life and death.  Once this gets extended
world-wide the permanent damage is done if the slightest error is included
in the code.

Who wants the responsibility for the loss of life of an American Soldier
sometime in the future for a "little ole goof in software?"  The USNG has a
theoretical justification in that it "will be used in the future for rescue
operations."  Maybe so, maybe no.  It certainly was NOT used for Katrina
because there's a UTM Zone change in the middle of the city of New Orleans.

Mice and men folks; the USNG is a dog and civilian implementation of the
MGRS will eventually get some young men killed.  Within the U.S., some may
remember the Twenty-nine Palms incident - that was only an entire U.S. town
that almost got bombed with live ordinance ... thank goodness for a break
in the clouds and not the MGRS!

I think it's a stupid idea (USNG), and I have said so publically for over a
decade since its original publication.  But what do I know about the use of
coordinate systems, anyway?

USNG is an FGDC standard:
