   * `NedelecPreBasisFactory` provides a basis for the Nedelec function space.
   * `NedelecL2InterpolationFactory` provides the linear functionals.
   *
   * `Defaultbasisfactory::create` first builds the function space and the linear functionals.
   * Then the constructor of `BasisMatrix` gets called. There the matrix
   *
   * \begin{equation}
   *   A_{i,j} := N_j(\phi_i)
   * \end{equation}
   *
   * with linear functionals $N_j$ and basisfunctions $\phi_i$ gets assembled.
   * Then the matrix gets inverted and is then used as a coefficent matrix for the standard monomial basis.
   *
   * For more details on the theory see the first chapter "Construction of Local Finite Element Spaces Using the Generic Reference Elements"
   * of the book "Advances in Dune" by Dedner, Flemisch and Klöfkorn published in 2012.
