An implementation of
SEssentialsTabBarProtocol that scrolls left and right to hold more tabs that can be fit on screen at once.
@property (assign, nonatomic) SEssentialsTabbedView *parentTabbedView
This implementation of
SEssentialsTabBarProtocol uses the flow layout control to render the tabs and manage the positioning of them.
The layout control is embedded in a scroll view to allow it to pan through the tabs and the ordering and reordering
of the tabs is managed by the flow control.
