This reverts commit c5bea524.

Detecting surface incursions as well as protrusions.

When a cell size is requested for a point outside the surfaces, the nearest
surface size is used to avoid an inappropriate return of the default size.

Truncating point to double before adding displacement vector to avoid memory use
growth (a linear growth for gcc 4.5 - bug, see CGAL mailing list 17/1/2011, but
grows regardless).

User controlled repeat limit.

Removing depricated triangulation hierarchy, using Fast_location.

Renamed typedef HTriangulation->Delaunay.

Any use of point in conformalVoronoiMesh must now be fully scoped as Foam::point
- there is a function called point() in the new version of Triangulation_3.h.

A point very close to the face of a tri was erroneously triggering it.
