Hi there,

I recently moved from my own distance calculating code to geokit and found that the calculations differ on one point - the earth's mean radius.

Geokit uses a mean radius of 6376.77 km / 3963.19 mi

Wikipedia says 6371 km / 3959 mi (http://en.wikipedia.org/wiki/Earth_radius)

What do you base the current geokit numbers on? Would you be open to changing it?

Keep up the good work!
Martin
