title: leaflet remove specific marker
body: <p>I am very new to use Leaflet and its plugins. Currently I am working with a project to mark a specific location in the map with a marker.</p>
  
  <p>But somehow I do not know how can I remove specific marker from the map if there are multiple markers.</p>
  
  <p>Markers are bind to pop-ups with some information and a button in the box. Therefore, my aim here is to remove the specific marker after the button is clicked.</p>
  
  <pre><code>var popupContent =
      '&lt;p&gt;Some Infomation&lt;/p&gt;&lt;/br&gt;' +
      '&lt;p&gt;' + date + '&lt;/p&gt;&lt;/br&gt;' +
      '&lt;button onclick=clearMarker()&gt;Clear Marker&lt;/button&gt;';
  
  myMarker = L.marker([lat, lng], { icon: redMarker, draggable: false });
  var myPopup = myMarker.bindPopup(popupContent, { closeButton: false });
  map.addLayer(myMarker);
  </code></pre>
  
  <p>Please let me know if there any improvement in the way I add the markers (Pretty sure there is better way to achieve that).    </p>
