Detailed Description

Checks for multiple patch faces on same cell and combines them. Multiple patch faces can result from e.g. removal of refined neighbouring cells, leaving 4 exposed faces with same owner.

Rules for merging:

only boundary faces (since multiple internal faces between two cells not allowed anyway)
faces have to have same owner
faces have to be connected via edge which are not features (so angle between them < feature angle)
outside of faces has to be single loop
outside of face should not be (or just slightly) concave (so angle between consecutive edges < concaveangle

E.g. to allow all faces on same patch to be merged:

combinePatchFaces 180 -concaveAngle 90
