2 * <h1>Graph package</h1>
4 * The graph package provides a general very simple abstraction of a graph.
5 * It was developed for the IOC container to represent dependences between
6 * components through their required and provided interfaces.
8 * The graph package supports a number of simple graph traversal operations, graph
9 * extension operations, and a visitor pattern.
11 * The main abstractions are:
13 * <li> {@link Graph}: The graph itself. </li>
14 * <li> {@link Node}: A node of a graph. </li>
15 * <li> {@link Edge}: An edge of a graph> </li>
16 * <li> {@link Visitor}: A visitor for implementing various operations on a graph. </li>
17 * <li> {@link EdgeFactory}: For extending the graph with new edges </li>
