Implement the keywords det and inv in the variational formulation language

• det(matrix expression) : compute the determinant of the matrix expression
• inv(matrix expression) : compute the inverse of the matrix expression

for example

integrate( elements(mesh), det(mat<2,2>( cst(1.), cst(0), cst(0), cst(1.0) ). evaluate() should produce the measure of the domain and det(mat<2,2>( cst(1.), cst(0), cst(0), cst(1.0) ) compute the determinant of the identity matrix 2x2

This issue was updated by revision 4ffc1bd.

the det keyword is implemented, it remains to do the inv() keyword in a
similar fashion

This issue was updated by revision 85c0d31.

now the keyword det() is available for the variational formulation language

store for each quadrature point the determinant of the matrix
started implementation of the inverse of a matrix of expressions and store
also the results for each quadrature points (will allow huge speedup in case
of linear and bilinear forms)
this is all necessary for 3D Winslow

The change for this is done now.See doc/manual/tutorial/mymesh.cpp for some examples
