radio button tab set with only one tab rendered should not show button

This looks pretty silly, if you ask me:

If due to conditional rendering only one tab exists, the radio buttons for the tabset shouldn’t be rendered at all.

Or we should be able to say whether it shows or not.  Kind of like a section header.  I use single tabs sometimes (mainly to use the tab shown action framework) and don’t always want the tab header to show either, but I can’t get rid of it.  But sometimes I might want to see it…

Perfect solution, Chandra.
