ZigZag Line

["Todd Marshall" <timza1221 gmail com>]

Somehow I can get the ZigZag line to be what I want. But I don't know
how I do it.
Just two segments with an arrow at one end (used for flowchart)
------->
|
|
|

or
____
|
|
|
V

Somehow I have to Add Segments and Delete Segments to get a double
that stays correct.
probably could create some kind of object to do the same thing?
