Start on some improvements to distributed mesh refinement
Add test for marker refinement
Add to test.py
Prevent redundant marking/communication
Switch 3D parallel refinement to Plaza algorithm
Reduce data sent in MPI
Merged master into chris/parallel-refinement-improvements
Start adding weights to SCOTCH partitioner
Add node weights to LocalMeshData
Merge branch 'master' into chris/parallel-refinement-improvements
Merged master into chris/parallel-refinement-improvements
Merge branch 'master' into chris/parallel-refinement-improvements
make dual graph from existing Mesh
allow dual_graph(Mesh) also to work in serial
Add partitioning method for Mesh to ParMETIS too
Fix typo
merge
fix typo
Update documentation and add test
Change series attributes to a more sensible format
