HELargeCenterTabBarController is a 100% Swift implementation of a UITabBarController with a lager center tab.
HELargeCenterTabBarController is a 100% Swift implementation of a UITabBarController with a lager center tab.
The center tab can be used in the typical manner where a tap switches to display the associated ViewController, or the center tab can be used in an alternate manner where the tap does not switch ViewControllers but instead executes a target-action.

Simple. Lightweight. To-the-point.
