IMPORTANT : 3D Delaunay Meshing now acts on connected volumes
	  separately, allowing to mesh regions that are not connected
	  topologically but that may intersect geometrically

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
