 * VisModelManager
 * INTENT: VisModelManager object is a top-level manager for the LiveWidgetModel and its sub-managers.
 * It has an api for use by external callers and the renderer.
 * TODO: The functionality in this class should be investigated and moved into more focused sub-objects.
 *
 * The VisModelManager owns VisDataSlots and VisProperties that the renderer pieces render,
 * interactivity modifies and save persists.
 *
 * It also has utilities to ease access for Visualization items to data-oriented actions
 * (like querying/filtering).
