Support for cell-volume interpolation during time sub-cycling now provided and
used in the MULES VoF solver to allow sub-cycling on morphing meshes.

Much more robust. Also now works on triSurfaces with non-compact point numbering.

isoSurfaceCell instead isoSurface.

Specifies motion as a set of interpolations on subsets of the mesh.

Only in PstreamBuffers mode. This makes sure that data from other processors
already handled gets deleted.

(less memory)

The optional 'average' switch causes use of the average-of-pointvalues
instead of the original volField.

Is more convergent&stable than switching.

The dummyThirdParty tree builds libraries which are drop-in
(but non-functional) versions of some thirdparty libraries. This will
make it easier to ship binary versions without having to ship thirdparty packs.

It uses mpicc to find out where the installed libraries are.

This signals that we are using the system installed openmpi version.
