The geoid (measured in meters) is used in calculating the redistribution
of global water, in a way directly analagous to uplift. Furthermore, the
iteration over elastic uplift now includes instantaneous changes to the
local geoid in redistribution. The geoid is calculated by dividing the
calculated gravitational potential by the negative of the surface
gravity (negative because a shift down in potential implies the
equipotential corresponding to the ocean surface has shifted up, to a
place previosly of higher potential). The gravity is hardcoded as the
surface value from PREM, which should be reconsidered. Additionally,
when rotation is added, this will have to be amended.

Gravity is measured in mGals (Gal is the cgs unit representing cm/s^2).
