Add a validation code in MetricBasis to check that the process: "computation of Bézier coeff, subdivision and interpolation" is correct for Metric (thus also for Jacobian in 3D).

Test of metric as a shape measure. It uses the slot Rho instead of adding a new slot, define METRICSHAPEMEASURE in GmshDefines.h to activate !

TODO : avoid topological unconsistencies for (e.g.) cones when
delaunay meshing is involved.

- can loop over Print.Parameter and provide script using that parameter
- can preview animation

* New version of Trevor Strickler's QuadTri patch (+ examples in benchmarks/extrude_quadtri)

* First pass at SU2 mesh export

Removed the -q option in initial mesh generation (generates meshes that do not respect size field)

added new subelements types for each of : point, line , triangle & tetrahedron e.g. for use with the xfem.

with tet meshes using pyramids.

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

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 !!

- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

order 7->9 seem to be wrong : the way shape functions are
computed is maybe numerically unstable
 

* basic Abaqus INP mesh export
