// ------------------------------------------------------------------------
// std::map
//
// The aim of all that follows would be to integrate std::map with
// Ruby as much as possible, namely, to allow the user to pass and
// be returned Ruby hash maps.
// const declarations are used to guess the intent of the function being
// exported; therefore, the following rationale is applied:
//
//   -- f(std::map<T>), f(const std::map<T>&), f(const std::map<T>*):
//      the parameter being read-only, either a Ruby hash or a
//      previously wrapped std::map<T> can be passed.
//   -- f(std::map<T>&), f(std::map<T>*):
//      the parameter must be modified; therefore, only a wrapped std::map
//      can be passed.
//   -- std::map<T> f():
//      the map is returned by copy; therefore, a Ruby hash
//      is returned which is most easily used in other Ruby functions
//   -- std::map<T>& f(), std::map<T>* f(), const std::map<T>& f(),
//      const std::map<T>* f():
//      the map is returned by reference; therefore, a wrapped std::map
//      is returned
