	The Structures_Graph class represents a graph data structure. A Graph is a data structure composed by a set of nodes, connected by arcs. Graphs may either be directed or undirected. In a directed graph, arcs are directional, and can be traveled only one way. In an undirected graph, arcs are bidirectional, and can be traveled both ways.
