+       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.

+       Files are deal.II/include/fe/fe_q_hierarchical.h and

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
