Contains bathymetry data used to interpolate the depth onto the Voronoi points only
if the IntDepth parameter is set to 1. Otherwise the depth is set in `initialization.c`

.
The spacing of the data is arbitrary since the interpolation routine searches for the
nearest neighbors to perform the interpolations. Note that the absolute value of the depth
is read in from this file, so SUNTANS does not distinguish between elevation and depression.
