fem

- The PetscFE object

- The basis function values and derivatives at quadrature points

T->T[0] = B[(p*pdim + i)*Nc + c] is the value at point p for basis function i and component c

T->T[1] = D[((p*pdim + i)*Nc + c)*dim + d] is the derivative value at point p for basis function i, component c, in direction d

T->T[2] = H[(((p*pdim + i)*Nc + c)*dim + d)*dim + e] is the value at point p for basis function i, component c, in directions d and e
