=head1 NAME

Array::Iterator::Reusable - A subclass of Array::Iterator to allow reuse of iterators

=head1 SYNOPSIS

  use Array::Iterator::Reusable;
  
  # create an iterator with an array
  my $i = Array::Iterator::Reusable->new(1 .. 100);
  
  # do something with the iterator
  my @accumulation;
  push @accumulation => { item => $iterator->next() } while $iterator->hasNext();
  
  # now reset the iterator so we can do it again
  $iterator->reset();

=head1 DESCRIPTION

Sometimes you don't want to have to throw out your iterator each time you have exhausted it. This class adds the C<reset> method to allow reuse of an iterator. This is a very simple addition to the Array::Iterator class of a single method.

=head1 METHODS

This is a subclass of Array::Iterator, only those methods that have been added are documented here, refer to the Array::Iterator documentation for more information.
