/**
 * @name MarkerWithLabelOptions

 *  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 bottom.)
 * @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.
 * @property {boolean} [labelVisible] A flag indicating whether the label is to be visible.
 *  The default is <code>true</code>. Note that even if <code>labelVisible</code> is
 *  <code>true</code>, the label will <i>not</i> be visible unless the associated marker is also
 *  visible (i.e., unless the marker's <code>visible</code> property is <code>true</code>).
