- constrain multiple normals per point
- introduce special cyclic type nonuniformTransformCyclic inbetween zones

Relaxation and solution parameters for the final iteration in PIMPLE loops are
now selected according to the value of the "finalIteration" entry in the
mesh::data dictionary.

rhoPimpleFoam significantly updates and now replaces rhoPisoFoam.

overlap.

Matching wall collision records by storing and comparing location of
wall impact relative to paticle centre.

Both sides need to use the same tag so it is now calculated as
    nProcs*(max(myProcNo,neighProcNo) + min(myProcNo,neighProcNo)
which is
- commutative
- does not interfere with normal message tag 1

collision step to be skipped for the NoBinaryCollision model.

Updated dsmc and md tuts, including new cyclic handling.

Removed Mattijs specific unitTestCases directory and moved CHANGES-splitCyclic into the doc/changes directory.

Doubles time taken to inject when used, as cells being found twice.

account of nParticles to expand the effective parcel size for
collision.
