Detailed Description

An Equivalence Relation for shared_state (shared_ptr<const state*>).

This is meant to be used as a comparison functor for an unordered_map whose keys are of type shared_state.

For instance here is how one could declare a map of shared_state

// Remember how many times each state has been visited.
std::unordered_map<shared_state, int,
                   state_shared_ptr_hash,
                   state_shared_ptr_equal> seen;
