// std::multiset
// 
// The aim of all that follows would be to integrate std::multiset with 
// Python as much as possible, namely, to allow the user to pass and 
// be returned Python tuples or sets.
// const declarations are used to guess the intent of the function being
// exported; therefore, the following rationale is applied:
// 
//   -- f(std::multiset<T>), f(const std::multiset<T>&):
//      the parameter being read-only, either a Python sequence or a
//      previously wrapped std::multiset<T> can be passed.
//   -- f(std::multiset<T>&), f(std::multiset<T>*):
//      the parameter may be modified; therefore, only a wrapped std::multiset
//      can be passed.
//   -- std::multiset<T> f(), const std::multiset<T>& f():
//      the set is returned by copy; therefore, a Python sequence of T:s 
//      is returned which is most easily used in other Python functions
//   -- std::multiset<T>& f(), std::multiset<T>* f():
//      the set is returned by reference; therefore, a wrapped std::multiset
//      is returned
//   -- const std::multiset<T>* f(), f(const std::multiset<T>*):
//      for consistency, they expect and return a plain set pointer.
