-- Minimal number of reference space (at least for tet, tri and quad)
     -- Automatic generation of these reference space
     -- New interface
     -- Modification of TriNodeBasis accordingly

** Need to compute Dof permutations automaticaly

** All Basis are commented (exept for TriNodeBasis)

** WARNING: Memory leak somewhere

Reworking ReferenceSpace -- Trying to have minimum reference space -- find permutation and reference space for 2d and tet

Working on Dof Reordering -- New GroupOfDof Interface -- Cleaning some tabs (replaced by spaces) -- BasisLagrange Implementation of Function and Grad

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.

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

Prepatation for Lagrange ReferenceSpace + correct consteness + cleaning some tabs -- replaced by spaces

QuadEdgeBasis: OK -- QuadBasis Convergence: OK \o/ -- Need a sexy way to handle the fact that QuadBasis are BILinear: need more integration points

QuadReferenceSpace + ReferenceSpace::inorder(): Seems OK \o/ -- Adding QuadLagrange -- Now all LagrangeBasis are using pointsGenerator

Minor Fix: TriNodeBasis face functions -- Add QuadFaces to ReferenceSpace -- QuadNodeBasis: Edges OK -- QuadFace: Orientation is *WRONG*

Fix: 2D Cells are now *FACES* (correct Dof for 2D - 3D interfaces) -- Nedelec Basis are now of order 0

Removing concept of ElementData: not general enough -- Adding GroupOfJacobian: sexier -- Revert to by group assembly -- *BUT* weak() takes elementID: up to now use one sort at the beginning -- Need to fix that

Removing FunctionSpace={node,edge,} -- FunctionSpace{scalar,vector,} can be instanciated the way we want (well, one basis only up to now)
