New members

These members are not defined in the Assignable and Default Constructible requirements, but are specific to queue.

Member	Description
value_type	The type of object stored in the queue. This is the same as T and Sequence::value_type.
size_type	An unsigned integral type. This is the same as Sequence::size_type.
bool empty() const	Returns true if the queue contains no elements, and false otherwise. Q.empty() is equivalent to Q.size() == 0.
size_type size() const	Returns the number of elements contained in the queue.
value_type& front()	Returns a mutable reference to the element at the front of the queue, that is, the element least recently inserted. Precondition: empty() is false.
const value_type& front() const	Returns a const reference to the element at the front of the queue, that is, the element least recently inserted. Precondition: empty() is false.
value_type& back()	Returns a mutable reference to the element at the back of the queue, that is, the element most recently inserted. Precondition: empty() is false.
