// FindState (multiple names version)
//
// Finds a state that matches as many of the supplied names as possible.
// A state with more names than those provided does not match.
// A state with fewer names can match if there are no states with the exact
// same number of names.
//
// The search proceeds like this. For the current class, keeping matching
// names until there are no more. If both the argument list and the state
// are out of names, it's an exact match, so return it. If the state still
// has names, ignore it. If the argument list still has names, remember it.
