This recipe demonstrates dialog.SelectSegments, a new call which replaces the "user pick" option from GUI recipes.

At the moment, there are a few problems with the highlighting when a segment is selected.

The first segment selected is not highlighted.

If the second segment selected comes after the first segment (higher segment number), the first segment selected is highlighted. Clicking the same second segment again clears the highlighting on the first segment.

If the second segment selected comes before the first segment, the second segment is correctly highlighted.

The correct segments are actually selected in each case, it's just that the visuals are confusing.

Another problem is that the selection can be hard to see with certain coloring options. For example, with "rainbow" coloring, a selection in the blue part of the protein is pretty much invisible. Switching to "CPK" or "EnzDes" coloring gets around that issue.
