title: Hide unused nodes after filtering
body: <p>To create separate models for separate years (year is an attribute in the edges table), I am trying to use filters. Using the filter <blockquote>Attribute > Equal > year <em>string (Edge)</em></blockquote> I am able to hide edges that are not from that year. However, that leaves me with unconnected nodes (see image for explanation).</p>
  
  <p>Is there any way to filter these (without removing nodes/edges that are relevant to the year-filter)? I am using Gephi 0.9.1.</p>
