title: Leaflet.js: is it possible to filter geoJSON features by property?
body: <p>I'm looking around and I see a lot of information about how to show/hide layers.  That's cool, but since I can add arbitrary properties to GeoJSON features, I kind of expect to be able to filter them accordingly.</p>
  
  <p>For instance, if I have features 1, 2 &amp; 3 with these properties:</p>
  
  <ol>
  <li>small | red | sweet</li>
  <li>large | green | sour</li>
  <li>small | red | hot</li>
  </ol>
  
  <p>How would I filter them by size? Or by color or flavor?</p>
