double-ended-queue (Deque)

Extremely fast double-ended queue (deque) implementation in JavaScript, version 2.1.0-0. Uses a circular buffer for O(1) operations on both ends, including random access via .get(). Outperforms native Array for shift/unshift even with V8's small array optimization. Suitable as stack, queue, or deque. No dependencies. Last release was a pre-release; library may be in maintenance mode.
