Fixes to point insertion, making faceAreaWeight normalised, not hard coded to cell size, adding tweak to fertex removal criteria to allow selective insertion at short-edge midpoint if the vertices have not already been flagged for removal.

Added point removal for short Delaunay edges in rotational controller as well as small and highly conntected dual cell removal.

Added point insertions on long edges for rotational controller and identified possible point removal candidates.

even when the dot-product of the Reynolds stress and the gradient of velocity is
negative.  Currently this is done by taking the magnitude, another alternative
would be to take only the positive part.

Better properties for CH4N2O
Limiting the temperature to the boiling-point in parcel

Writing out of a pointField along with the mesh - allows restarts.  Added FCC and BCC initial conditions (commented), their duals are rhombic dodecahedra and bitruncated octahedra respectively.
