+<center><div align="center">

+</div>
+</center> <p>The boxes in the above graph have the following meaning:  </p>
+<ul>
+<li>
+A filled gray box represents the struct or class for which the graph is generated. </li>
+<li>
+A box with a black border denotes a documented struct or class. </li>
+<li>
+A box with a grey border denotes an undocumented struct or class. </li>
+<li>
+A box with a red border denotes a documented struct or class forwhich not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries. </li>
+</ul>
+<p>The arrows have the following meaning:  </p>
+<ul>
+<li>
+A dark blue arrow is used to visualize a public inheritance relation between two classes. </li>
+<li>
+A dark green arrow is used for protected inheritance. </li>
+<li>
+A dark red arrow is used for private inheritance. </li>
+<li>
+A purple dashed arrow is used if a class is contained or used by another class. The arrow is labeled with the variable(s) through which the pointed class or struct is accessible. </li>
+<li>
+A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labeled with the template parameters of the instance. </li>
