/**
 * A class to manage the extensions and prosemirror interactions within the

 *
 * @remarks
 *
 * The RemirrorManager enables the lifecycle methods of the extensions by
 * calling each method in the distinct phases of the lifecycle.
 *
 * - `onCreate` - This happens when the manager is constructed. It calls on the
 *   extension which have an `onCreate` method and allows them to do their work.
 *
 * For the built in methods, this is when the `SchemaExtension` creates the
 * Schema and when the `TagsExtension` combines the tags for the editor
 * instance.
 *
 * ```ts
 * const manager = Manager.create(() => [
 *   new DocExtension(),
 *   new TextExtension(),
 *   new ParagraphExtension(),
 * ])
 * ```
 *
 * At this point all the `onCreate` methods have been called. Including the
 * `onCreate` for the `Schema`.
 *
 * - `onView` - This is called the framework instance connects the
 *   `RemirrorManager` to the ProseMirror EditorView.
 *
 * ```ts
 * manager.addView(new EditorView(...))
 * manager.store.commands.insertText('Hello world');.
 * ```
 *
 * - [[`onStateUpdate`]] - This is the method called every time the ProseMirror
 *   state changes. Both the extensions and the `Framework` listen to this event
 *   and can provide updates in response.
