[Proj] PyProj API question

[Charles Karney]

The documentation says that the distance is in meters.  If you
initialize the Geod object with

   g = Geod(a = 180/math.pi, f = 0)

then you'll be treating a sphere with circumference 360, so you
can then think of the distance as being arc length (in degrees).
