Detailed Description

Hash Function for state pointers.

This is meant to be used as a hash functor for an unordered_map whose keys are state pointers. For instance here is how one could declare a map of state*.

// Remember how many times each state has been visited.
std::unordered_map<spot::state*, int, spot::state_ptr_hash,
                                 spot::state_ptr_equal> seen;
