Detailed Description

Class which is used to hold information about the grid.

The grid is simply a spacing between allowable points. When objects are "Snapped" to the grid, all points must then lie on the grid lines. This is used within GeoLib to manage degenerate cases but has other applications. Also used to record degenerate errors. All functions are static.
