Line From Center Extension

@DanRathbun

He had to draw (with the LineTool) a temporary vertical line between the outer vertex of one to the other, and then use a midpoint inference to draw a horizontal line denoting the center between the 2 holes.

In a related thread, I envisioned an extension that, behind the scenes, drew just such a line to provide a temporary midpoint inference, deleting it automatically at the end of the action. Such a line might look a bit like hidden geometry so you can see that it has been briefly created. I have no idea if such a thing is even possible!
