-The approach used below creates a hierarchy: Dimension is subservient to Line.

-Does this solve our problem of connected objects? Maybe, partially. Let's think this
-through. It only works for endpoints, not points in the middle...
-
-Also: this is bad, depending on the Draw() function to update the internal
-      position(s) of the data of the object! (is it though?)
-
 How to move: click once moves only the object/point clicked on, all connected
 objects deform themselves accordingly. click twice selects ALL connected objects;
 all objects move as a unified whole.
