Detailed Description
template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HGRAD_WEDGE_I2_FEM< Scalar, ArrayScalar >
Implementation of an H(grad)-compatible FEM basis of degree 2 on Wedge cell.
Implements Lagrangian basis of degree 2 on the reference Wedge cell. The basis has
cardinality 15 and spans an INCOMPLETE bi-quadratic polynomial space. Basis functions are dual
to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:

\remark Ordering of DoFs follows the node order in Wedge<15> topology. Note that node
order in this topology does not follow the natural oder of k-subcells where the nodes
are located, except for nodes 0 to 5 which coincide with the vertices of the base
Wedge<6> topology. As a result, L_0 to L_5 are associated with nodes 0 to 5, but
L_6 to L_14 are not associated with edges 0 to 9 in that order.
