This package provides utility routines for handling integer sets and maps.

The main classes are IntSet which represents a set of 32-bit integers (int values), IntIterator which is an iterator over a sequence of 32-bit integers, IntHashMap which is a map from 32-bit integers to arbitrary objects, and IntToIntMap which is a map from 32-bit integers to 32-bit integers.

The package name is a pun on the conventional use by mathematicians of the symbol Z to denote the set of all natural integers.
