> * Use ArrayDeque instead of LinkedList
> * Replace an ArrayList that was being used as a queue with ArrayDeque
> * Improve write single byte method to hard-code sizes and save time

> Resizable-array implementation of the Deque interface. Array deques have no capacity restrictions; they grow as necessary to support usage. They are not thread-safe; in the absence of external synchronization, they do not support concurrent access by multiple threads. Null elements are prohibited. This class is *likely to be* ... *faster than LinkedList when used as a queue.*
