/**
 * @name SplitPane
 *
 * @description
 * SplitPane is a component that makes it possible to create multi-view layout.
 * Similar to iPad apps, SplitPane allows UI elements, like Menus, to be
 * displayed as the viewport increases.
 *
 * If the devices screen size is below a certain size, the SplitPane will
 * collapse and the menu will become hidden again. This is especially useful when
 * creating an app that will be served over a browser or deployed through the app
 * store to phones and tablets.
 *
 * @usage
 * To use SplitPane, simply add the component around your root component.
 * In this example, we'll be using a sidemenu layout, similar to what is
 * provided from the sidemenu starter template.
 *
 *  ```html
 *  <ion-split-pane>
 *    <!--  our side menu  -->
 *    <ion-menu [content]="content">
 *      <ion-header>
 *        <ion-toolbar>
 *          <ion-title>Menu</ion-title>
 *        </ion-toolbar>
 *      </ion-header>
 *    </ion-menu>
 *
 *    <!-- the main content -->
 *    <ion-nav [root]="root" main #content></ion-nav>
 *  </ion-split-pane>
 *  ```
 *
 *  Here, SplitPane will look for the element with the `main` attribute and make
 *  that the central component on larger screens. The `main` component can be any
 *  Ionic component (`ion-nav` or `ion-tabs`) except `ion-menu`.
 *
 *  ### Setting breakpoints
 *
 *  By default, SplitPane will expand when the screen is larger than 768px.
 *  If you want to customize this, use the `when` input. The `when` input can
 *  accept any valid media query, as it uses `matchMedia()` underneath.
 *
 *  ```
 *  <ion-split-pane when="(min-width: 475px)">
 *
 *    <!--  our side menu  -->
 *    <ion-menu [content]="content">
 *    ....
 *    </ion-menu>
 *
 *    <!-- the main content -->
 *    <ion-nav [root]="root" main #content></ion-nav>
 *  </ion-split-pane>
 *  ```
 *
 *  SplitPane also provides some predefined media queries that can be used.
 *
 *  ```html
 *  <!-- could be "xs", "sm", "md", "lg", or "xl" -->
 *  <ion-split-pane when="lg">
 *  ...
 *  </ion-split-pane>
 *  ```
 *
 *
 *  | Size | Value                 | Description                                                           |
 *  |------|-----------------------|-----------------------------------------------------------------------|
 *  | `xs` | `(min-width: 0px)`    | Show the split-pane when the min-width is 0px (meaning, always)       |
 *  | `sm` | `(min-width: 576px)`  | Show the split-pane when the min-width is 576px                       |
 *  | `md` | `(min-width: 768px)`  | Show the split-pane when the min-width is 768px (default break point) |
 *  | `lg` | `(min-width: 992px)`  | Show the split-pane when the min-width is 992px                       |
 *  | `xl` | `(min-width: 1200px)` | Show the split-pane when the min-width is 1200px                      |
 *
 *  You can also pass in boolean values that will trigger SplitPane when the value
 *  or expression evaluates to true.
 *
 *
 *  ```html
 *  <ion-split-pane [when]="isLarge">
 *  ...
 *  </ion-split-pane>
 *  ```
 *
 *  ```ts
 *  class MyClass {
 *    public isLarge = false;
 *    constructor(){}
 *  }
 *  ```
 *
 *  Or
 *
 *  ```html
 *  <ion-split-pane [when]="shouldShow()">
 *  ...
 *  </ion-split-pane>
 *  ```
 *
 *  ```ts
 *  class MyClass {
 *    constructor(){}
 *    shouldShow(){
 *      if(conditionA){
 *        return true
 *      } else {
 *        return false
 *      }
 *    }
 *  }
 *  ```
 *
