+ Extended: The <code

+ Extended: The <code
+ class="class">TriaAccessor<1></code>::<code
+ class="member">operator ==</code> function is now overloaded by
+ <code class="class">TriaObjectAccessor<1,dim></code> for
+ <code>dim>1</code> to allow the identification of a line with
+ its duplicate.

+
+ <li> <p>
+ Extended (internal): Lines on <code>level>0</code> have always
+ been stored pairwise. In order to allow the creation of
+ duplicate lines we now also allow storage of single lines. The
+ <code class="class">TriangulationLevel<1></code>::<code
+ class="member">reserve_space</code> function now takes an
+ additional <code>n_consecutive_lines</code> parameter which
+ allows to create new single as well as pairs for lines
+ (<code>n_consecutive_lines=1</code> or
+ <code>n_consecutive_lines=1</code>, respectively.

Changed: When allowing anisotropic refinement it cannot be
garantueed that all children of a cell are stored in
