- uniformize names of new api functions
- remove unnecessary args (dim, nbrIntegrationPoints, ...)
- cleanup ElementType::functions

fast curving 2: curve boundary element column by column and then one by one, going from the inside to the outside. For each element: base nodes are fixed, top nodes are optimized such that the thickness of the element is preserved.

Computation of anisotropy measure put inside qualityMeasureJacobian framework. Keeping MetricBasis for now but will be removed someday.

Bézier coefficients computed for the product of two or three functions are now ordered as the original convention (corner coefficients are the first)

new qualityMeasuresJacobian.h/cpp files for computing Jacobian-based validity and qualities. Validity moved from AnalyseCurvedMesh (see next commit). New: Scaled Jacobian (for hexes and quads). Remains to move the anisotropy quality measure from metricbasis.

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.
