PHP Класс HTMLPurifier_Queue, yii

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.
