A Stepper element outputs a repeating sequence of Director (Switch) events
as it is triggered by incoming Director events with specified marks set.
Arriving marks that correspond to any specified in the output sequence
will reset the sequence to that point (before any step).
<P>
Only Director data generated by special modules, such as
<A HREF="TriggerSwitch">TriggerSwitch</A> can be used to drive
the element.  A single director event can contain more than one code
value.
<h4>
Input
</h4>
<UL Type="none">
<LI> <B>Step Control</B> -- Director input (Non-switch data is ignored)
</UL>
<h4>
Outputs
</h4>
<UL Type="none">
<LI> <B>Switch Out</B> -- Stepped Director events
<LI> <B>Step Control</B> -- Pass-through of Director input
</UL>

<h4>
Control Panel
</h4>
This has two columns of check boxes and one of radio buttons, with 16 rows
-- one for each possible director code.

<B>Columns:</B>
<UL Type="none">
<LI> <B>Step:</B>
 -- Marks that will cause step -- current mark is output, next is primed.
<LI> <B>Set:</B> -- Specifies sequence of marks to be stepped through.
(Arriving marks in this group will also reset sequence to that mark.)
<LI> <B>Curr:</B> -- Current mark (must be on one of the <B>Set:</B> group
for output to occur).
</UL>
