/**
* @name Input
* @module ionic
* @description
*
* `ion-input` is a generic wrapper for both inputs and textareas. You can give `ion-input` attributes to tell it how to handle a child `ion-label` component.
*
* @property [fixed-label] - a persistant label that sits next the the input
* @property [floating-label] - a label that will float about the input if the input is empty of looses focus
* @property [stacked-label] - A stacked label will always appear on top of the input
* @property [inset] - The input will be inset
* @property [clearInput] - A clear icon will appear in the input which clears it
*
* @usage
* ```html
* <ion-input>
* <ion-label>Username</ion-label>
* <input type="text" value="">
* </ion-input>
*
* <ion-input clearInput>
* <input type="text" placeholder="Username">
* </ion-input>
*
* <ion-input fixed-label>
* <ion-label>Username</ion-label>
* <input type="text" value="">
* </ion-input>
*
* <ion-input floating-label>
* <ion-label>Username</ion-label>
* <input type="text" value="">
* </ion-input>
