Highlight feature in search: color each node by search

[bkmartinjr]

It would be ideal if each "search" that had highlighting on used a different color, not all "blue".

Perhaps the "highlight" (raindrop) button could show the color being used by that search term, so it was obvious which vertices matched which search.

Idea from Arathi: a hover on the filter or the colorby on the right search bar will de-emphasize all other nodes and edges that don't match the filter. This suggestion avoids a simple problem with multi-color: what to do about nodes that match both 'kidney' and 'neuron', for instance
