title: How to change the color of results from leaflet-knn on the map
body: <p>I have displayed the the result markers for the leaflet-knn on the map with following code:</p>
  
  <pre><code>const myloc = new L.LatLng(13.7433242, 100.5421583);
  
  var gjLayer = L.geoJson(testCities, {
      onEachFeature: function(feature, layer) {
          content = "&lt;b&gt;Name:&lt;/b&gt; " + feature.properties.name;
          layer.bindPopup(content);
      }
  });
  
  var longitude = myloc.lng,
      latitude = myloc.lat;
  
  var res = leafletKnn(gjLayer).nearest(
              [longitude, latitude], 5, distance);
  
  for (i = 0; i &lt; res.length; i++) {
      map.addLayer(res[i].layer);
  }
  </code></pre>
  
  <p>Now I want to change the color of this marker that is added or I want to change the icon. </p>
  
  <p>Can anybody tell me how can I do?</p>
