Grid Builder

1. When interpolation Zmap points to grid cell properties, ignore null values of the 4 Zmap points that surround the grid cell center point of interest. Only set the grid cell center point of interest to null if all Zmap points are null.  Previously, if any of the 4 points were null, then the grid cell center point was assigned null too.  This will reduce the number of grid cell points that have null values compared to the previous release.
