+ Change && to ||, as if a face is small the area calculation can
  differ on opposing processors

+ Do not calculate transform with NOORDERING

+ Make intersection and nearest functions functors. This makes adding
  different intersection and nearest routines easier.
+ treeDataPrimitivePatch takes its tolerance as a constructor argument
+ Make treeDataTriSurface a typedef of treeDataPrimitivePatch

If geometricTestOnly is set to true then edges will not be marked as region
edges, only as internal or external edges. If there are any edges still
marked as regions then this is because they are non-manifold.
