- was merging all boundary points originating from the same point
- which caused merging of multiple extruded points (since all originating
  from the same point)
- there is no more addressing available from addPatchCell layer so
  instead do a geometric merge
- additional bug: calculating weights if faceZone on processor patch

Fixed #55.

It was ignoring the initial selection of cells inside/outside the refinement
region and instead looking at all surface-intersection regardless. Fixes #51.

Internal values get set but never swapped on processor boundaries. Fixes #49.

     Changing to adjustableTimeStep the tutorial reactingTwoPhaseEulerFoam/laminar/bubbleColumnIATE

Fixes #45

This is more logical - the points are passed in sorted as well and there is
no way for the master sampledset to determine the ordering.
