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