/**
* @name Segment
* @description
* A Segment is a group of buttons, sometimes known as Segmented Controls, that allow the user to interact with a compact group of a number of controls.
* Segments provide functionality similar to tabs, selecting one will unselect all others. You should use a tab bar instead of a segmented control when you want to let the user move back and forth between distinct pages in your app.
* You could use Angular's `ngModel` or `FormBuilder` API. For an overview on how `FormBuilder` works, checkout [Angular Forms](http://learnangular2.com/forms/), or [Angular FormBuilder](https://angular.io/docs/ts/latest/api/forms/index/FormBuilder-class.html)
