/**
 *  SplitViewNavigator is a component responsible for displaying multiple
 *  ViewNavigators at the same time in a single container.  SplitViewNavigator
 *  takes ViewnNavigatorBase objects as children and lays them out as
 *  defined by its <code>layout</code> property.  This component is useful for 
 *  creating a master/detail interface on a mobile device. There is no limit to
 *  the amount of child navigators this component can manage. 
 * 
 *  <p>If the <code>autoHideFirstViewNavigator</code> property is set to
 *  <code>true</code>, the SplitViewNavigator will automatically hide the
 *  navigator that is at index 0 when the top level application has a
 *  portrait aspect ratio.  The navigator will be redisplayed when the
 *  application is reoriented into a landsacpe orientation.  A developer
 *  can manually hide and show a navigator by toggling the <code>visble</code>
 *  flag on the child.  When set, the <code>includeInLayout</code> property
 *  of that child will be set to match.</p>
 *    
 *  <p>SplitViewNavigator adds the additional functionalilty of temporarily 
 *  displaying the first navigator inside a Callout component.  When the
 *  <code>showFirstViewNavigatorInCallout()</code> method is called, the
 *  first navigator is displayed in a callout until the
 *  <code>hideViewNavigatorCallout()</code> method is called, or the user
 *  touches outside the bounds of the callout.  It is important to note that
 *  when a navigator is displayed in a callout, it is reparented as a child of
 *  that container.  This means using IVisualElementContainer methods such as
 *  <code>getElementAt()</code> on SplitViewNavigator may not return the 
 *  expected results.  If a developer wants to access the first or second 
 *  navigator, it is recommended that they use the <code>getViewNavigatorAt()</code> 
 *  method.  These will always return the correct navigator regardless of whether 
 *  a navigator is in a callout or not.</p>
