Consider ways to improve distinguishing bi-directional relationships

[pglewis]

If a Pod has many relationships it can become difficult to tell which of the connections the bidirectional arrowhead belongs to. Ideas:

1. Mouse-over on arrowhead highlights the link and related Pod
2. Different stroke color for bi-directional link connections

Currently using dotted for one-way and solid for bi-directional.

Mouse-over is still a good idea.

Might be a little more clear if it were a double line for bi-directional. Not sure how much of a pain in the ass that would be.

Setup a pod with a fair number or relationships and you'll see my concern... there can a lot of connecting lines and I fear double lines will make it that much trickier to get the "at a glance" part.

Regardless of any dictatorial decisions I make on the defaults, #15 is around to ensure you'll be able to override them. Since the drawing library is SVG you'll also be able to directly target elements via CSS. Stylesheets actually have a higher priority than element attributes for SVG, the complete opposite to stylesheets for HTML.
