a hash-queue, where the values are of type 'a
invariant t checks the invariants of the queue.
create () returns an empty queue.
clear the queue
mem q k returns true iff there is some (k, v) in the queue.
lookup t k returns the value of the key-value pair in the queue with
key k, if there is one.
enqueue t k v adds the key-value pair (k, v) to the end of the queue,
returning `Ok if the pair was added, or `Key_already_present
if there is already a (k, v') in the queue.
first t returns the front element of the queue, without removing it.
keys t returns the keys in the order of the queue.
dequeue t returns the front element of the queue.
dequeue_with_key t returns the front element of the queue and its key
dequeue_all t ~f dequeues every element of the queue and applies f to each
one.
remove q k removes the key-value pair with key k from the queue.
replace q k v changes the value of key k in the queue to v.
iter t ~f applies f to each key and element of the queue.
