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).

(2) Make pyramid's points and monomials ready for differenciation of subdivision-ready and optimization-ready basis
(3) Correction number lagragian bezier coeff for pyramids p1

+ add jacobianOrder(..)

make bezierBasis independant from declaration of element tag in GmshDefines.
move static methods getTag(..) & **FromTag(..) from MElement to ElementType.
completely revert to double for monomials.

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

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

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.

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

AnalyseCurvedMesh development (should work in all cases, edit PluginManager.cpp to activate the plugin)

AnalyseCurvedMesh development (works for triangle and tetra but is not yet optimized and is still incomplete, edit PluginManager.cpp to activate the plugin)
