 \brief Graph structures implemented in Hugo.

 Hugolib provides several data structures to meet the diversing requirements

 of the possible users.

 In order to save on running time or on memory usage, some structures may

 fail to provide

 some graph features like edge or node deletion.

 Hugolib also offers special graphs that cannot be used alone but only

 in conjunktion with other graph representation. The examples for this are

 \ref EdgeSet, \ref NodeSet, and the large variety of graph wrappers.

 You are free to use the graph structure that fit your requirements

 the best, most graph algorithms and auxiliary data structures can be used

 with any graph structures.
