Detailed Description

   template<typename _Tp, typename _Alloc = allocator<_Tp>>
       class std::forward_list< _Tp, _Alloc >" A standard container with linear time access to
       elements, and fixed time insertion/deletion at any point in the sequence.

       Template Parameters:
           _Tp Type of element.
           _Alloc Allocator type, defaults to allocator<_Tp>.

       Meets the requirements of a container, a sequence, including the optional sequence
       requirements with the exception of at and operator[].

       This is a singly linked list. Traversal up the list requires linear time, but adding and
       removing elements (or nodes) is done in constant time, regardless of where the change
       takes place. Unlike std::vector and std::deque, random-access iterators are not provided,
       so subscripting ( [] ) access is not allowed. For algorithms which only need sequential
       access, this lack makes no difference.

       Also unlike the other standard containers, std::forward_list provides specialized
       algorithms unique to linked lists, such as splicing, sorting, and in-place reversal.

       typename  = std::_RequireInputIter<_InputIterator>> void std::forward_list< _Tp, _Alloc
       >::assign (_InputIterator __first, _InputIterator __last) [inline]
       Assigns a range to a forward_list.

       Parameters:
           __first An input iterator.
           __last An input iterator.

       This function fills a forward_list with copies of the elements in the range
       [__first,__last).

       Note that the assignment completely changes the forward_list and that the number of
       elements of the resulting forward_list is the same as the number of elements assigned.

   template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc

       Parameters:
           __n Number of elements to be assigned.
           __val Value to be assigned.

       This function fills a forward_list with __n copies of the given value. Note that the
       assignment completely changes the forward_list, and that the resulting forward_list has
       __n elements.

           __il An initializer_list of value_type.

       Replace the contents of the forward_list with copies of the elements in the
       initializer_list __il. This is linear in il.size().

       std::forward_list< _Tp, _Alloc >::emplace_after (const_iterator __pos, _Args &&... __args)
       [inline]
       Constructs object in forward_list after the specified iterator.

       This function will insert an object of type T constructed with

   template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator std::forward_list< _Tp,
       _Alloc >::erase_after (const_iterator __pos) [inline]
       Removes the element pointed to by the iterator following pos.

       Parameters:
           __pos Iterator pointing before element to be erased.

       Returns:
           An iterator pointing to the element following the one that was erased, or end() if no
           such element exists.

       This function will erase the element at the given position and thus shorten the
       forward_list by one.

       Due to the nature of a forward_list this operation can be done in constant time, and only
       invalidates iterators/references to the element being removed. The user is also cautioned
       that this function only erases the element, and that if the element is itself a pointer,
       the pointed-to memory is not touched in any way. Managing the pointer is the user's
       responsibility.

   template<typename _Tp, typename _Alloc = allocator<_Tp>> iterator std::forward_list< _Tp,
       _Alloc >::erase_after (const_iterator __pos, const_iterator __last) [inline]
       Remove a range of elements.

       Parameters:
           __pos Iterator pointing before the first element to be erased.
           __last Iterator pointing to one past the last element to be erased.

       Returns:
           @ __last.

       This function will erase the elements in the range (__pos,__last) and shorten the
       forward_list accordingly.

       This operation is linear time in the size of the range and only invalidates
       iterators/references to the element being removed. The user is also cautioned that this
       function only erases the elements, and that if the elements themselves are pointers, the
       pointed-to memory is not touched in any way. Managing the pointer is the user's

       only invalidates iterators/references to the element being removed.
