DiscreteGlobalBasisFunction as basis for DOFVector
dune-functions several data-structures exist, that may be a good basis for the implementation of
DOFVectors. Currently, a DOFVector is parametrized with a global function-space basis, e.g.
Dune::PQkNodalBasis and has internal vector datastructure, for holding DOF coefficients.
On the other hand a
Dune::DiscreteGlobalBasisFunction is parametrizes with a global function-space basis, a tree-path, a vector container, and a
NodeToRangeEntry. Currently I don't know what's the meaning of
It can construct a
LocalFunction that can be evaluated at local coordinates in the element. The basis and the coefficients can be accessed and maybe in the future an evaluation at global coordinates might be implemented.
