+       New: There are now a set of functions

+  <li> <p>
+       New: The classes 
+       <code class="class">Patterns::Integer</code>
+       and <code class="class">Patterns::Double</code> now allow that
+       a range may be specified in which the parameter shall
+       be. Furthermore, instead of a class,
+       <code class="class">Patterns</code> is now a namespace, so it
+       can be reopened in case you want to write another pattern class
+       and want to put it into the same namespace.

+       New: <code class="class">class DerivativeApproximation</code>
