Tab
============

Minimalistic but extensible tab swapper. It can be used to create a tab swapper as well as a galerie slideshow. 
you can have effects like **Moostack**, the [barack slideshow](https://devthought.com/wp-content/moogets/BarackSlideshow/demo.html) or [jQuery nivoslider](https://nivo.dev7studios.com/) or whatever you want by providing an animation plugin.
