 Each graph structure in LEMON provides two standard map templates called
 \c EdgeMap and \c NodeMap. Both are reference maps and you can easily
 assign data to the nodes and to the edges of the graph. For example if you
-have a graph \c G defined as
+have a graph \c g defined as
 \code
-  ListGraph G;
+  ListGraph g;
 \endcode
 and you want to assign a floating point value to each edge, you can do
 it like this.
 \code
-  ListGraph::EdgeMap<double> length(G);
+  ListGraph::EdgeMap<double> length(g);
 \endcode
 Note that you must give the underlying graph to the constructor.

 An alternative way to define maps is to use \c MapBase
 
-\todo For this, \c MapBase seems to be a better name then \c NullMap.
