 * @description
 * A `md-list-item` element can be used to represent some information in a row.<br/>
 *
 * @usage
 * ### Single Row Item
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### Multiple Lines
 * By using the following markup, you will be able to have two lines inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-2-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * It is also possible to have three lines inside of one list item.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-3-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *       <p>Third Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * ### Secondary Items
 * Secondary items are elements which will be aligned at the end of the `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">
 *       Secondary Button
 *     </md-button>
 *   </md-list-item>
 * </hljs>
 *
 * It also possible to have multiple secondary items inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">First Button</md-button>
 *     <md-button class="md-secondary">Second Button</md-button>
 *   </md-list-item>
 * </hljs>
 *
 * ### Proxy Item
 * Proxies are elements, which will execute their specific action on click<br/>
 * Currently supported proxy items are
 * - `md-checkbox` (Toggle)
 * - `md-switch` (Toggle)
 * - `md-menu` (Open)
 *
 * This means, when using a supported proxy item inside of `md-list-item`, the list item will
 * become clickable and executes the associated action of the proxy element on click.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-checkbox class="md-secondary"></md-checkbox>
 *   </md-list-item>
 * </hljs>
 *
 * The `md-checkbox` element will be automatically detected as a proxy element and will toggle on click.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-switch class="md-secondary"></md-switch>
 *   </md-list-item>
 * </hljs>
 *
 * The recognized `md-switch` will toggle its state, when the user clicks on the `md-list-item`.
 *
 * It is also possible to have a `md-menu` inside of a `md-list-item`.
 * <hljs lang="html">
 *   <md-list-item>
 *     <p>Click anywhere to fire the secondary action</p>
 *     <md-menu class="md-secondary">
 *       <md-button class="md-icon-button">
 *         <md-icon md-svg-icon="communication:message"></md-icon>
 *       </md-button>
 *       <md-menu-content width="4">
 *         <md-menu-item>
 *           <md-button>
 *             Redial
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-item>
 *           <md-button>
 *             Check voicemail
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-divider></md-menu-divider>
 *         <md-menu-item>
 *           <md-button>
 *             Notifications
 *           </md-button>
 *         </md-menu-item>
 *       </md-menu-content>
 *     </md-menu>
 *   </md-list-item>
 * </hljs>
 *
 * The menu will automatically open, when the users clicks on the `md-list-item`.<br/>
 *
 * If the developer didn't specify any position mode on the menu, the `md-list-item` will automatically detect the
 * position mode and applies it to the `md-menu`.
 *
 * ### Avatars
 * Sometimes you may want to have some avatars inside of the `md-list-item `.<br/>
 * You are able to create a optimized icon for the list item, by applying the `.md-avatar` class on the `<img>` element.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <img src="my-avatar.png" class="md-avatar">
 *     <span>Alan Turing</span>
 * </hljs>
 *
 * When using `<md-icon>` for an avater, you have to use the `.md-avatar-icon` class.
 * <hljs lang="html">
 *   <md-list-item>
 *     <md-icon class="md-avatar-icon" md-svg-icon="avatars:timothy"></md-icon>
 *     <span>Timothy Kopra</span>
 *   </md-list-item>
 * </hljs>
 *
 * In cases, you have a `md-list-item`, which doesn't have any avatar,
 * but you want to align it with the other avatar items, you have to use the `.md-offset` class.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-offset">
 *     <span>Jon Doe</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### DOM modification
 * The `md-list-item` component automatically detects if the list item should be clickable.
 *
 * ---
 * If the `md-list-item` is clickable, we wrap all content inside of a `<div>` and create
 * an overlaying button, which will will execute the given actions (like `ng-href`, `ng-click`)
 *
 * We create an overlaying button, instead of wrapping all content inside of the button,
 * because otherwise some elements may not be clickable inside of the button.
 *
 * ---
 * When using a secondary item inside of your list item, the `md-list-item` component will automatically create
 * a secondary container at the end of the `md-list-item`, which contains all secondary items.
 *
 * The secondary item container is not static, because otherwise the overflow will not work properly on the
 * list item.
 *
