This script was written by Sunjay Varma - www.sunjay-varma.com
This script has two main classes:
Tab - Basic tab used by TabBar for main functionality
TabBar - The tab bar that is placed above tab bodies (Tabs)
It uses a pretty basic structure:
root
-->TabBar(root, init_name) (For switching tabs)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
etc.
