det J is not necessary positive now (which is correct)

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

ENABLE_SWIG has been replaced by ENABLE_WRAP_PYHTON and ENABLE_WRAP_JAVA.

Fragmentation in progress

Added option for levelset cutting ""CutMeshTri(tag)", that saves only triangles and tets (no polygons or polyhedra)
Added new level set definition "Levelset Points(tag)={{x1,y1,z1},{x2,y2,z2}};", builds a level set from a set of data points using RBF interpolation

- 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
 

Added MElement::integrate, MElement::integrateCirc,
MElement::integrateFlux in similar fashion as in deprecated
Post/shapeFunctions.h

Integration of p-covector fields to riemann.

Lift And Drag better, but dgFunctionEvaluator returns some out of range values (bbox ?, precision ?)

better quad meshing

MElement : correct bug in 1d jacobian (please check this commit is correct, I'm surprise such a bug survived so long unnoticed)

integration points (order 8 meshes 10 times faster) + correct a bug in
dg for non iso-parametric in implicit
