// ------------------------------------------------------------------------
// std::set
// 
// const declarations are used to guess the intent of the function being
// exported; therefore, the following rationale is applied:
// 
//   -- f(std::set<T>), f(const std::set<T>&):
//      the parameter being read-only, either a sequence or a
//      previously wrapped std::set<T> can be passed.
//   -- f(std::set<T>&), f(std::set<T>*):
//      the parameter may be modified; therefore, only a wrapped std::set
//      can be passed.
//   -- std::set<T> f(), const std::set<T>& f():
//      the set is returned by copy; therefore, a sequence of T:s 
//      is returned which is most easily used in other functions
//   -- std::set<T>& f(), std::set<T>* f():
//      the set is returned by reference; therefore, a wrapped std::set
//      is returned
//   -- const std::set<T>* f(), f(const std::set<T>*):
//      for consistency, they expect and return a plain set pointer.
