 // RemovingTabModel
 //  After a tab is removed from the TabStrip2's model, the model can no longer
 //  provide information about the tab needed to update the display, however the
 //  TabStrip2 continues to display the tab until it animates out of existence.
 //  During this period, this model serves as a dummy. It is created and assigned
 //  to the tab when the tab is removed from the model and owned by the Tab2.
