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