Better Zoltan Hypergraph support.

  • Communication weight given separately from (computational) weight
  • Hyperedges determined based on selected user neighborhood, with using the communication weight of the cell as the edge weight and every cell considering that cell as its neighbor as vertices
  • Automagical hierarchical partition, partitioning nodes via hypergraph and processes via RIB

Hypergraph and hierarchical partitioning depend on fixes to Zoltan crashes in sandialabs/Zoltan#6. The hypergraph crash can be circumvented by setting NUM_LID_ENTRIES to 1. Hierarchical partition doesn't crash on the master branch on all setups.
