title: Move markers using mouse in angular google maps
body: <p>I am doing an angular project.It contains a google map using <a href="https://angular-ui.github.io/angular-google-maps/#!/" rel="nofollow noreferrer">angular-google-maps</a>.So on this map,the user can add many <code>markers</code>.</p>
  <p><strong>app.js</strong></p>
  <pre><code>angular.module('mapAngular', ['uiGmapgoogle-maps'])
      .controller('MainCtrl', function($scope) {
          angular.extend($scope, {
              map: {
                  center: {
                      latitude: 42.3349940452867,
                      longitude: -71.0353168884369
                  },
                  zoom: 11,
                  markers: [],
                  events: {
                      click: function(map, eventName, originalEventArgs) {
                          var e = originalEventArgs[0];
                          var lat = e.latLng.lat(),
                              lon = e.latLng.lng();
                          var marker = {
                              id: Date.now(),
                              coords: {
                                  latitude: lat,
                                  longitude: lon
                              }
                          };
                          $scope.map.markers.push(marker);
                          console.log($scope.map.markers);
                          $scope.$apply();
                      }
                  }
              }
          });
      });
  </code></pre>
  <p><strong>HTML</strong></p>
  <pre><code>&lt;div&gt;
      &lt;ui-gmap-google-map center=&quot;map.center&quot; zoom=&quot;map.zoom&quot; draggable=&quot;true&quot; events=&quot;map.events&quot;&gt;
          &lt;ui-gmap-marker ng-repeat=&quot;m in map.markers&quot; coords=&quot;m.coords&quot; icon=&quot;m.icon&quot; idkey=&quot;m.id&quot;&gt;&lt;/ui-gmap-marker&gt;
      &lt;/ui-gmap-google-map&gt;
  &lt;/div&gt;
  </code></pre>
  <p>The map will shows all added markers.I need a feature to move this markers dynamically by using mouse.Please give me a valuable guideline to this?
  Thanks</p>
