Monomials order changed !
Points of Prism p>2 changed !
3D Serendipity elements have now nodes only on edges !

Modify gmshGeneratePoints.
All validated.

Warning : Points for high order prisms will change ! Old version is incoherent with what is done with other elements 

Optimized generic computation of scaled Jacobian range in MElement. Adapted AnalyseCurvedMesh plugin as well as generic distoShapeMeasure to use it. 

Fixed bug (wrong basis type) in OptHOM. Fixed bug in computation of Bergot basis gradient, still wrong.

Re-organized and cleaned up nodalBasis/polynomialBasis/JacobianBasis. Enabled higher-order bases for prisms. Fixed and completed shape functions and Jacobian for pyramids. Fixed bug in computation of Bezier exponents for hexahedra. TODO: OptHOM bug with pyramids to be fixed, clean-up of bases (point generation) to be completed.

gmsh: Added functions to nodalBasis for dg to compile. (I Think) those functions should be there and not in polynomialBasis, as they are general to any base.
dg: switch from polynomialBasis to nodalBasis

Implementation of high order pyramids. Introduces nodalBasis as a parent class of polynomialBasis and pyramidalBasis.

serendip and non serendip)

Introduce MPI in NonLinearMechSolver

- 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
