AND-OR graph data structures and algorithms.

The main data structure, [Graph], is a bipartite graph of AND nodes (representing rules in a proof system) and OR nodes (representing propositions in a proof system). [Graph]s have a designated goal OR node that represents the goal to be proven.

A convenient way to construct and store these graphs is to use the [From<jsongraph::Graph>] trait implementation in [Graph]. Otherwise, AND-OR graphs can be created with [Graph::new].
