Discuss potential additional features

[bentsherman]

Now that BioDepVis has been refactored, we can begin to think about additional features. This depends mainly on what the end users want, and so we may need to give them time to play with the visualization and see what they think of. Some ideas that have been discussed so far:

• Karan's "ROI mode", which allows you to select two clusters and just display them and their corresponding alignments
• Some way to "filter" the graphs so that only selected nodes (which could be based on a search query or a selected GO term, etc.) and their alignment edges are shown
• Search term operators such as AND, OR, and NOT
