title: PagerTabStrip - center the tabs, or make them fit
body: <p>I'm using this library <a href="https://github.com/astuetz/PagerSlidingTabStrip" rel="nofollow noreferrer">https://github.com/astuetz/PagerSlidingTabStrip</a> to create a PagerTabStrip.</p>
  
  <p>My output <img src="https://i.stack.imgur.com/jAPfG.png" alt="enter image description here"></p>
  
  <p>You can see that after my tabs I have some empty space.
  I want to make the tabs fit all the screen, or at least center the tabs.
  Is that possible?</p>
