- CGAL itself includes its library dependencies, we only need to
  provide the -L... option to the proper ThirdParty locations.

  Should help improve general build robustness.

Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=1186

This reverts commit e4c14096.

This reverts commit e4c14096.

This is so that surfaceFeatureExtract will compile without boost/mpfr

Removed unused dependencies on CGAL

BUG: Wrong decision about wellInside.

STYLE: Rename variable - maxLevels to minLevels - better description.

COMP: Add decomp libs.

default whern surface does not support volumeType.

BUG: conformalVoronoiMesh.  Making test "totalHits >= hitLimit" rather than
"totalHits = hitLimit" to be strictly consistent and always trigger
the iteration termination message.

CGAL_LIBS.

problems with the tensor::eigenValues calculation:

    "complex eigenvalues detected for tensor:"

for very high aspect ratio faces.

CGAL_SRC for everything.  Changed location of CGAL_FILES "files".

Updated old meshers with new options.

in .bashrc using this environment:

Ability to fill any initial points properly into any surfaces.  Using conformationSurfaces class to handle geometric queries to the surfaces to be conformed to.

Fixed mistake in spoke search - wasn't setting closestSpokeHitDistance for further comparisons.  Isotropic forcing using sqrt(faceArea).  Added 3D analogue of 2D forcing function  - needs experimented with.

Using CGAL-3.4.  Requires to be linked to compiled boost thread library.  In this commit it is hard-coded to -lboost_thread-gcc43-mt-1_37, i.e. boost version 1.37.0, will need to be parameterised.  CGAL does not need to be compiled, as before, and needs the CGAL-3.4/src/files file as before, but the compiler_config.h file, written by cmake, is now included from CGAL/3.4/include/CGAL, where it has been editted to remove the use of GMP.  To use the CMP libraries, add -lgmpxx -lmpfr -lgmp to Make/options - there is little (2%) obvious performance benefit to creating a DT with GMP.  -frounding-math is a required option  - when running in debug assertions failures occur without it when using an exact construction.
