/**
 * The `Fragment` class represents a chunk of DOM that is rendered once with Mithril and then takes
 * over control of its own DOM and lifecycle.
 *
 * This is very similar to the `Component` wrapper class, but is used for more fine-grained control over
 * the rendering and display of some significant chunks of the DOM. In contrast to components, fragments
 * do not offer Mithril's lifecycle hooks.
 *
 * Use this when you want to enjoy the benefits of JSX / VDOM for initial rendering, combined with
 * small helper methods that then make updates to that DOM directly, instead of fully redrawing
 * everything through Mithril.
 *
 * This should only be used when necessary, and only with `m.render`. If you are unsure whether you need
 * this or `Component, you probably need `Component`.
