Package overview for net.sf.saxon.z

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.
