   8  * SegmentControl object is a horizontal control made of multiple segments,
   9  * each segment item functioning as a discrete button. A segmented control affords a compact means to group together a number of controls.
  10  * A segmented control can display a title or an image. The UISegmentedControl object automatically resizes segment items to fit proportionally
  11  * within their superview unless they have a specific width set. When you add and remove segments,
  12  * you can request that the action be animated with sliding and fading effects.
