/**
 * A very simple, but useful stack (linked list).
 * <p>
 * It's one-way, threadsafe, fast, toString friendly, and can merge with other
 * SimpleStacks easily via {@link #consume(AbstractLinkedList)}
 * <p>
 * Note that neither remove() nor size() are not supported.
 * <p>
 * If you need a list or a map, use one. This class is for pushing together
 * references, iterating through them, and maybe joining them into a string.
