drawing edges
I got it so that the edge when drawn doesn't pass into the circle representing the node.
 I got the edges so that they are drawn outside of the nodes. In otherwords..they don't pass into the circles that represnt nodes.
just playing with my_test()
the edges are being kept in a hash inside of the nodes
small touches
clean up some code
fixed a bug where I was setting the wrong boolean flag inside of an edge.
added two functions node.can_go_to_other_side() and node.get_other_node()
