* \brief The local dual p1 finite element on simplices

* Note that if the dual functions are chosen to be dual on the faces,
* the integrated product of a Lagrange \f$\lambda_p\f$ and dual
* function \f$\theta_q\f$ over faces not containing \f$q\f$ does in
* general not vanish.

* \tparam D Domain data type
* \tparam R Range data type
* \tparam dim Dimension of the simplex
* \tparam faceDual If set, the basis functions are bi-orthogonal only on faces containing the corresponding vertex.
