void first() Make first radiobutton in a group

Clicking any radiobutton in a group will set that button and clear the other buttons in the group without effecting buttons in other groups.

This must be called for the first radiobutton of the first group if there will be more than one group.

This must be called before constructing the other buttons in the group.
