/**
 * @name Icon
 * @description
 * Icons can be used on their own, or inside of a number of Ionic components.
 * For a full list of available icons, check out the
 * [Ionicons docs](../../../../ionicons).
 *
 * One feature of Ionicons in Ionic is when icon names are set, the actual icon
 * which is rendered can change slightly depending on the mode the app is
 * running from. For example, by setting the icon name of `alarm`, on iOS the
 * icon will automatically apply `ios-alarm`, and on Material Design it will
 * automatically apply `md-alarm`. This allows the developer to write the
 * markup once while Ionic applies the appropriate icon based on the mode.
 *
 * @usage
 * ```html
 * <!-- automatically uses the correct "star" icon depending on the mode -->
 * <ion-icon name="star"></ion-icon>
 *
 * <!-- explicity set the icon for each mode -->
 * <ion-icon ios="ios-home" md="md-home"></ion-icon>
 *
 * <!-- always use the same icon, no matter what the mode -->
 * <ion-icon name="ios-clock"></ion-icon>
 * <ion-icon name="logo-twitter"></ion-icon>
 * ```
 *
 * @demo /docs/demos/src/icon/
 * @see {@link /docs/components#icons Icon Component Docs}
