adding a geometry math class
fixing merge error
commiting near working code for determining if a point is inside fo a polyhedron.  code does not compile and wrapper layer to generate face and vert arrays for each grain/field is still needed
workign through the geometry math functions and trying to institute our mesh structures where possible for consistency
adding a filter to try to see if the sampling of a surface mesh is working
commiting working code and filter to sample surface mesh with set of points. algorithm produces correct answer, but is slow.  Some profiling would help determine slow spots.
