Tabs Demo - creating relative next and previous buttons

[mcollins323]

I am working on a mutli step form that gets spread across tabs?

I am using angularui and I have the form split up into 4 tabs.

How do I create relative buttons to go to next and previous. Also have them not appear if first or last tab.

Code from demo.

Thanks for any assistance.
