 * Hydrate or render existing server-rendered markup inside of a `container` element.

 * More than one hydration sub-tree may be present in the same `container`.
 * Use `options.renderBefore` to identify placement of the hydration sub-tree,
 * otherwise the last sub-tree in `container` will be targeted.
 *
 * Hydration sub-trees are demarcated by `<!--lit XXXXXXXXX-->` and `<!--/lit-->` comment nodes.
 * Sub-trees may be nested and hydrated separately at a later time, as for example with custom element child content.
