Stop Plugin
Example:
<!-- Stop at this slide.
(For example, when used on the last slide, this prevents the
presentation from wrapping back to the beginning.) -->
<div class="step stop">
The stop plugin is a pre-stepleave plugin. It is executed before
impress:stepleave event. If the current slide has class="stop"
set, it will disable the next() command by setting the next slide to the current
slide.
