The type of count-min tables

Core functions
val init : int -> int -> t

``init l w`` generates a table with length ``l`` and width ``w``, all counters initialized to 0.

val incr : int -> int -> t -> unit

``incr i j t`` increments the counter at length index ``i`` and width index ``j`` in table ``t``.

val get : int -> int -> t -> int

``get i j t`` gets the value of the counter at length index ``i`` and width index ``j`` in table ``t``.

val clone : t -> t

``clone t`` returns a new table with the same contents as ``t``.

val merge : t -> t -> t

``merge t1 t2`` merges tables ``t1`` and ``t2`` element-wise. If ``t1`` and ``t2`` have the same dimensions, returns a new table whose elements are the sums of corresponding elements from ``t1`` and ``t2``. If dimensions do not match, raises ``INVALID_ARGUMENT``.
