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

JF

cross field computataion ok in 2D
high order tools bugs fixed
wing-spline is now a correct geometry
meshing in two passes is now permitted (like in bamg)

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

No commit message

GetStatistics for 2D meshes gives now mean value quality also

* new option to recombine all tri meshes, whatever the specific setting for a given surface
* libmatch -> libblossom (there's a libMatch.dylib in the default MacOS install)

the status messages that slow down the mac gui

we could try to copy a mesh before generating the source mesh

don't mesh GVertices in the constructor: this has nasty side effects when
loading geos+mesh+new post-processing datasets

-> Mesh0D in Generator

Please test: this change could have unexpected consequences... :-)

in GUI to avoid flood of messages on mailing list (thx to Dave for this)

optimizing 3D meshes without also optimizing 2D meshes with Lloyd

introduced mesh.optimizeLloyd to fix this

No commit message

2d meshing algo with -optimize does lloyd optim (tri or quad optim algo depending if recombine is selected)

Propose to automatically create .geo file with a Merge command when
trying to append a scripting command to a non-geo file. Got the idea 
after the discussion with Robert Bou. (This is better than scripting
the Merge command IMHO.)

- invert #define logic (HAVE_MESH, HAVE_POST, HAVE_SOLVER, ... instead of HAVE_NO_MESH,
  HAVE_NO_POST, HAVE_NO_SOLVER)

CreateTopologyFromMesh more accurate
Possibility to partition also Faces and not only GModels

never ever change the immutable vertex numbers: otherwise we cannot use
our algorithms from outside with prescribed boundary meshes

-> use MVertex::_index instead

(renamed setNum to forceNum to make sure we don't use setNum by mistake)
