     *
     * @brief The Graph Memory Segment contains directed graphs. The graph consists of nodes with poses and edges between them.
     * The poses in the nodes and the edges are used for platform navigation. Additionally, thee nodes are used for symbolic planning.
     * One segment can contain multiple graphs. They distinguished by their *scene*-name.
     * See Slice API documentation for GraphMemorySegmentBase.
