ArnaTabView class
Implements a tabbed layout and behavior structure.
The view lays out the tab bar at the top and the content below the tab bar.
A controller can be used to provide an initially selected tab index and manage subsequent tab changes. If a
controller is not specified, the view will create its own ArnaTabController and manage it internally.
Otherwise it's up to the owner of controller to call dispose on it after finish using it.
Tabs' contents are built with the provided tabs at the active tab index. Inactive tabs will be moved Offstage and their animations disabled.
