amr contour uses neighbor info from CTH for optimization
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
This branch adds an optimization to reuse neighbor data when running insitu with CTH. It requires extra data sent over from CTH, but does not do the all-to-all communication in ShareBlocks. Instead it only shares blocks between neighbor pairs.
The branch is amrcontour_uses_neighbor_info
