 **Reason for this change:**
 - It was difficult to have custom buttons since buttons automatically received the Ionic styles. The user can now take advantage of adding their own styling to a button if they want it to behave differently than the Ionic button.
-Keeping the `<a>` and `<button>` element and adding `ion-button` as an attribute gives us the ability to take advantage of the native functionality and built-in accessibility of native elements. If Ionic provided an `<ion-button>` we’d have to copy over all the possible attributes and events to the real nested button/link (`type=submit`, `formnovalidate`, `value`, `autofocus`, `href`, `target`, `focus`/`blur`, `download`, `nofollow`, `ping`, etc). Additionally, Angular 2 does not have the "replace" directive where `<ion-button>` could be turned into `<a ion-button>`.

 - Since `button` was already being used as an attribute to the `<a>` element, this is more consistent between the two.
 - If a navPush or navPop directive is on an `<a ion-button>`, Ionic can automatically add the `href` attribute.

  * 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.
