Thanks to Matvey Kraposhin

option for prismatic grid with same directions

not tested yet

For faster calculation of closest cluster, seems to be slower in
practice

Add algorithm to balance number of points among processors

Still have to add algorithm to balance number of points. each processor
works on

Testing algorithm before adding to partitioner

PrepareReceiveInner was not called for sparse tag

Possible fix in packtagdata/unpacktagdata - mismatch between amount of
calls to MPI_Pack and MPI_Unpack

GridTool for Kmeans clustering, should eventually move to Partitioner
class
