Very rough first implementation of parallel refinement in 2D
try to tidy up and simplify
more tidy up
adjusted demo to work with parallel refinement
Divided more generic refinement into new class, added support for set of sharing processes on edges. Prepare for 3D.
Fix up 3D uniform refinement (untested)
added 3d files
Added comments
Merge with trunk - now broken
some fixes - now compiles using MeshDistributed:compute_...
working again with new shared_entities structure
Fix bug in 3D refinement - revert GraphBuilder - new routine crashing...
some cleanup
merge and code simplification
Changed MPI call
Reincarnated GraphBuilder routine
clean up some junk
Work on 3d marker refine
Merge with trunk
Merge and fix build errors. Don't modify cmake.local - merges lead to problems.
