Coordinates tab selection between a CupertinoTabBar and a CupertinoTabScaffold.
The index property is the index of the selected tab. Changing its value updates the actively displayed tab of the CupertinoTabScaffold the CupertinoTabController controls, as well as the currently selected tab item of its CupertinoTabBar.
This samples shows how CupertinoTabController can be used to switch tabs in
CupertinoTabScaffold.
