=head2 C<increment>

Without arguments returns the current iterator increment size (number
of lines returned by iteraction). With an argument, changes the size
of the increment. The increment size can be changed while using the
iterator.

=head2 C<forward>

Forwards the iterator the offset specified. If the offset is too big
(as in, more iterations than the size of the iterator) the iterator is
set to the last element. It also supports negative offsets (but please
use the C<backward> method).

The new position index is returned.

=head2 C<backward>

Backwards the iterator the offset specified. If the offset is too big
(as in, more iterations than the current position of the iterator) the
iterator is set to the first element. It also supports negative offsets
(but please use the C<forward> method).

The new position index is returned.
