+ New: class <code class="class">FETools</code> performs
+ interpolations and extrapolations of discrete functions from one
+ <code class="class">FiniteElement</code> to another <code
+ class="class">FiniteElement</code>. It also provides the local
+ interpolation matrices that interpolate on each
+ cell. Furthermore it provides the interpolation difference
+ matrix id-I<sub>h</sub> that is needed for evaluating
+ (id-I<sub>h</sub>)z for e.g. the dual solution z.
