3.4 SpheremapB reads in the current shape model and uses it to calculate gravity and albedo data (2D grids and images) for a specific bigmap region.

This created a suite of data files for a bigmap (REFMAP).  It created a raw (simple binary file) of a 2D matrix for the scaled albedo (sample_ALB) and the topography (DTM).  It also created images (pgm format) of the albedo, topography and color scaled topography.
