/**
* @name MarkerWithLabelOptions
* @class This class represents the optional parameter passed to the {@link MarkerWithLabel} constructor.
* 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>).
