Reorganized computation and usage of scaled Jacobian in OptHOM, fixed bugs. Removed specific distortion/scaled Jacobian computation routines. 

not yet finished ... mesh smoothing has to be adapted 

Worked a lot oncurvilinear meshing : projection of point on surafces work, matching meshes andgeometry works better, added some test examples...

     boundary layers in 2D 
     periodi bug fixed
     many other stuff

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)

this is good stuff isn't it ;-)
 

high order smoother class added : high order meshes are guaranteed to be
valid : some elements are "un-curved" in order to ensure good value of
the distorsion mapping. P2 triangle quality estimate is robust

- 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
 

No commit message

- renamed functionSpace into polynomialBasis (functionSpace will be much higher level)

renamed most gmsh* classes

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)

- moved GUI to FlGui + added experimental QGui to test Qt

- fixed most MSVC and gcc compiler warnings

- converted some remaining tabs to whitespace (that's why the patch is
  so large; please try to remember to indent with 2 spaces and not
  tabs when you commit stuff to CVS)

- merged modified patch from Konstantinos Poulios to allow saving
  physical/partition as element tags in mesh formats that don't
  support them natively

Removed GSL dependency. Gmsh now uses blas and lapack for linear algebra
stuff.

- fix bb computation to avoid model jumping around when adding points in z=0 plane
- pass interpol matrices as ref
