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

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.

This reverts commit c600ce54.

- use GPL version 3

STYLE: move polyDualMesh from conversion -> manipulation

Still not good enough - only handles single extrusion vector per cyclic point.

wall interactions.

If it does, then make the wallImpactDistance 0, if it doesn't make it
d/2.

Adding pbFixed so nParticles is specified directly by the user, making
massTotal not determine anything in this case.

Removing unused private data member.

- improve documentation, use GPL version 3
