How to programmatically select active tab in UI builder

[Arch Henderson]

I'm trying to select a different tab in my Tab Set component, but I cannot find a way to do so. 

The component documentation mentions a 'Select tab index' property, but that property does not seem to exist or is not shown in the configuration panel. There has to be a way to select the active tab, right?

how would you set the active tab in a script.  for example if I am on tab 0 how would I change the active tab in an event?
