-/**
- * The `Component` class defines a user interface 'building block'. A component
- * generates a virtual DOM to be rendered on each redraw.
- *
- * Essentially, this is a wrapper for Mithril's components that adds several useful features:
- *
- *  - In the `oninit` and `onbeforeupdate` lifecycle hooks, we store vnode attrs in `this.attrs.
- *    This allows us to use attrs across components without having to pass the vnode to every single
- *    method.
- *  - The static `initAttrs` method allows a convenient way to provide defaults (or to otherwise modify)
- *    the attrs that have been passed into a component.
- *  - When the component is created in the DOM, we store its DOM element under `this.element`; this lets
- *    us use jQuery to modify child DOM state from internal methods via the `this.$()` method.
- *  - A convenience `component` method, which serves as an alternative to hyperscript and JSX.
- *
- * As with other Mithril components, components extending Component can be initialized
- * and nested using JSX, hyperscript, or a combination of both. The `component` method can also
- * be used.
- *
- * @example
- * return m('div', <MyComponent foo="bar"><p>Hello World</p></MyComponent>);
