spallart almaras is kinda working

orientation of quads is still to fix !

* store max vertex/element number on a per-model basis (removed globalNum in MVertex/MElement). This should be improved, but forcing a GModel in the MVertex and MElement constructors

* use filename as a "partition indicator" in readMED (for both meshes and views), so we can deal with DDM datasets in MED (MED does not store partition numbers)

a frame solver is made
changed INRIA MESH output
removed feaure in BL field
started to do MNT diagrams
 

fixed nasty bug in quad meshing
added parameters to BL generation (2D)

smoothing 1D mesh is now (maybe) correct

No commit message

     boundary layers in 2D 
     periodi bug fixed
     many other stuff

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

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 !!
