/**
* A simple array-backed queue, based off of the classic Okasaki
* persistent amortized queue. The basic idea is to maintain two
* stacks: an input stack and an output stack. When the output
* stack runs out, reverse the input stack and use it as the output
* stack.
*
* We don't use the SPL implementation because it's only supported
* on PHP 5.3 and later.
*
* Exercise: Prove that push/pop on this queue take amortized O(1) time.
*
* Exercise: Extend this queue to be a deque, while preserving amortized
* O(1) time. Some care must be taken on rebalancing to avoid quadratic
* behaviour caused by repeatedly shuffling data from the input stack
* to the output stack and back.
