+/**
+ * @name MarkerWithLabel for V3
+ * @version 1.1.9 [June 30, 2013]
+ * @author Gary Little (inspired by code from Marc Ridey of Google).
+ * @copyright Copyright 2012 Gary Little [gary at luxcentral.com]
+ * @fileoverview MarkerWithLabel extends the Google Maps JavaScript API V3
+ *  <code>google.maps.Marker</code> class.
+ *  <p>
+ *  MarkerWithLabel allows you to define markers with associated labels. As you would expect,
+ *  if the marker is draggable, so too will be the label. In addition, a marker with a label
+ *  responds to all mouse events in the same manner as a regular marker. It also fires mouse
+ *  events and "property changed" events just as a regular marker would. Version 1.1 adds
+ *  support for the raiseOnDrag feature introduced in API V3.3.
+ *  <p>
+ *  If you drag a marker by its label, you can cancel the drag and return the marker to its
+ *  original position by pressing the <code>Esc</code> key. This doesn't work if you drag the marker
+ *  itself because this feature is not (yet) supported in the <code>google.maps.Marker</code> class.

+ *  The properties available are the same as for <code>google.maps.Marker</code> with the addition
+ *  of the properties listed below. To change any of these additional properties after the labeled
+ *  marker has been created, call <code>google.maps.Marker.set(propertyName, propertyValue)</code>.
+ *  <p>
+ *  When any of these properties changes, a property changed event is fired. The names of these
+ *  events are derived from the name of the property and are of the form <code>propertyname_changed</code>.
+ *  For example, if the content of the label changes, a <code>labelcontent_changed</code> event
+ *  is fired.
+ *  <p>
+ * @property {string|Node} [labelContent] The content of the label (plain text or an HTML DOM node).
+ * @property {Point} [labelAnchor] By default, a label is drawn with its anchor point at (0,0) so
+ *  that its top left corner is positioned at the anchor point of the associated marker. Use this
+ *  property to change the anchor point of the label. For example, to center a 50px-wide label
+ *  beneath a marker, specify a <code>labelAnchor</code> of <code>google.maps.Point(25, 0)</code>.
+ *  (Note: x-values increase to the right and y-values increase to the top.)
+ * @property {string} [labelClass] The name of the CSS class defining the styles for the label.
+ *  Note that style values for <code>position</code>, <code>overflow</code>, <code>top</code>,
+ *  <code>left</code>, <code>zIndex</code>, <code>display</code>, <code>marginLeft</code>, and
+ *  <code>marginTop</code> are ignored; these styles are for internal use only.
+ * @property {Object} [labelStyle] An object literal whose properties define specific CSS
+ *  style values to be applied to the label. Style values defined here override those that may
+ *  be defined in the <code>labelClass</code> style sheet. If this property is changed after the
+ *  label has been created, all previously set styles (except those defined in the style sheet)
+ *  are removed from the label before the new style values are applied.
+ *  Note that style values for <code>position</code>, <code>overflow</code>, <code>top</code>,
+ *  <code>left</code>, <code>zIndex</code>, <code>display</code>, <code>marginLeft</code>, and
+ *  <code>marginTop</code> are ignored; these styles are for internal use only.
+ * @property {boolean} [labelInBackground] A flag indicating whether a label that overlaps its
+ *  associated marker should appear in the background (i.e., in a plane below the marker).
+ *  The default is <code>false</code>, which causes the label to appear in the foreground.

+ *  must be set to <code>false</code>.
+ * @property {boolean} [optimized] A flag indicating whether rendering is to be optimized for the
