#14 toggle non-reference genome proteins from display

[Kara Dolinski]

Not a big priority, but a nice feature would be to enable the toggling of the display/inclusion of the non-reference genome proteins in the PANTHER families--perhaps just displaying them as a dot by default or some such abbreviation. The larger PANTHER families can be tough to manage, and being able to remove/abbreviate the non-reference genome proteins would be great.
