1. 100 grid nodes are assigned to the longest direction.
2. The grid spacing is calculated for that direction:
        (Maximum-Minimum) / (# of Nodes – 1)
3. The same grid spacing is applied to the shorter direction.
4. The # of Nodes for the shorter direction is calculated:
        ((Maximum-Minimum) / Spacing) + 1
5. If the # of Nodes in the shorter direction is not greater than 4, then the minimum and maximum values in that direction will be adjusted so that there are at least 4 grid nodes. This means that for data sets where one direction has a vastly different range than the other direction, the grid extents may not exactly match the data extents.
