Added option for levelset cutting ""CutMeshTri(tag)", that saves only triangles and tets (no polygons or polyhedra)
Added new level set definition "Levelset Points(tag)={{x1,y1,z1},{x2,y2,z2}};", builds a level set from a set of data points using RBF interpolation

with tet meshes using pyramids.

It's not perfect (it introduces the pyramids in the extruded/transfinite mesh) but it's useful
nonetheless.

bug removed in GFaceCompound.cpp (sorry for that, Tristan, my fault)

Use the following in your Geo file
Mesh.RemeshParametrization=2; //(0) harmonic (1) conformal (2) Rbf

Simplified and cleanup GFaceCompound

The delquad algo is now much more stable and nice

Two 3D meshers have been added. 

One is an embryo of the 3D delhex mesh which is an extension of delquad.

The other one is MMG, the mobile mesh generator of CECILE DOBRZYNSKI (Bordeaux I) and PASCAL FREY (PARIS VI). We are very happy that this new anisotropic 3D mesher is now available as an open source !!

delete tets before subdivision: this fixes a bug when the non-subdivided mesh already contains tets, which
then appeared twice in the final mesh (reported by Thomas Cordaro)
