title: How can i set the new position of marker with Gmaps.js?
body: <p>With GMaps.js i can add markers easy way:</p>
  
  <pre><code>map.addMarker({  
                lat: -12.043333,
                lng: -77.028333
                });
  </code></pre>
  
  <p>After create that marker, i want to set him a new position after some time.
  For example my next code:</p>
  
  <pre><code>setInterval(function() {
       setNewPosition();
  }, 5000);
  
  setNewPosition(){   
     map.removeMarkers();
  
     map.addMarker({  
                    lat: -13.043333,
                    lng: -77.028333
                    });
  }
  </code></pre>
  
  <p>But i don`t want all time a removed marker, i want only set him a new position. That is the really possible? I know in google map it solved with <strong>google.maps.LatLng()</strong>
   and <strong>.setPosition()</strong>, but how in Gmaps.js they used?</p>
