New Proj.4 perl bindings

[rand at meridian-enviro.com]

I had found the proj.pm that Steven Lime let leak out on to the
mapserver mailing list (http://mapserver.gis.umn.edu/majordom_lists/archives/mapserver-users/html/0006/msg00131.html)
was somewhat awkward to use, so I decided to wrap my own.  Good ol'
free software thinking.  :)

I've just finished my first pass at wrapping the proj.4 library, here
is a summary:

   use Projection;

   my $pj = new Prection(["proj=merc", "ellps=clrk66", "lon_0=-96"], $DEGREES);
   ($u, $v) = $pj->Forward(-97.0667, 47.9000);
   ($lat, $lon) = $pj->Inverse($y, $v);

Thats it.

The projection is automatically destroyed, so there isn't a need to
free it. Also, I got rid of the projUV structure. Oh, and the
arguments to making a new projection are automatically counted. (If
you want the default behaviour of using (ugh) radians, just make the
second argument to Projection "$RADIANDS".)

If anybody has any suggestions on improving this, please let me
know. (Does anybody *really* want that projUV structure exported out
into perl?)

I've no documentation, test suite, or much else, yet. But go ahead,
hold your breath, I'll get back to you.  ;^)

Oh, the standard

   perl Makefile.PL
   make
   make install

should work.
