 * Component that renders event meta data in a structured way, with icons and labels.

 * for the default order in which the blocks will be rendered.
 *
 * As part of the blocks array you can also decide to render a custom React Component,
 * which will then also be rendered.
 *
 * Example:
 * const MyCustomBlock = () => <div>Something nice</div>;
 * <EventDetails event={event} blocks={[EventDetailBlocks.LOCATION, MyCustomBlock]} />
