C++11: Containers: forward_list

A singly linked list was added. Here is an example:

#include <forward_list>
#include <iostream>

int main()
{
  std::forward_list<int> myList{3};

  myList.push_front(0);
  myList.push_front(1);
  myList.push_front(2);

  std::forward_list<int>::iterator iter = myList.begin();

  for (int element : myList) std::cout << " " << element;

  std::cout << ": ";

  std::cout << *iter << " "; iter = ++iter;
  std::cout << *iter << " "; iter = ++iter;
  std::cout << *iter << " "; iter = ++iter;
  std::cout << *iter << " "; iter = ++iter;

  std::cout << ": ";

  std::cout << myList.front() << " "; myList.pop_front();
  std::cout << myList.front() << " "; myList.pop_front();
  std::cout << myList.front() << " "; myList.pop_front();
  std::cout << myList.front() << " "; myList.pop_front();
  std::cout << std::endl;
  return 0;
}
// Output:  2 1 0 3: 2 1 0 3 : 2 1 0 3
