.SH NAME
Iterator \- marks a position in a data structure
.SH SYNOPSIS
.B #include <Unidraw/iterator.h>
.SH DESCRIPTION
An iterator marks a position in a data structure, generally during a
traversal of some sort.  For example, an iterator keeps track of the
current position when iterating through a list of elements.  Unidraw's
Iterator class serves this purpose in conjunction with ULists or
objects that use them.
