New: Checked in new class <code class="class">FE_Q_Hierarchical</code>
derived from class <code class="class">FiniteElement</code>.
This element is analogous to <code class="class">FE_Q</code>, but
- makes use of hierachical, shape functions, based on the

<code class="class">Polynomials::Hierarchical</code> class.
- For degree>1, the non-nodal basis functions are "bubble" functions,
- which are not Lagrange polynomials. Therefore, the usual interpolation
- based on using unit support points will not work for degree>1.
- I plan to submit a different interpolation-projection operator soon,
- based on an hp-type interpolant.
