		An abstract interface to highly-parameterizable queues/deques.
		
		Background: There exists a feature space for queues that extends between:
		
		* simple, single-ended, non-concurrent, bounded queues
		
		* double-ended, threadsafe, growable queues
		
		... with important points inbetween (such as
		the queues used for work-stealing).
		
		This package includes an interface for Deques that allows the
		programmer to use a single API for all of the above, while using the
		type-system to select an efficient implementation given the
		requirements (using type families).
		
		This package also includes a simple reference implementation based
		on &#39;IORef&#39; and &quot;Data.Sequence&quot;.
