 * View upcast writer. It provides a set of methods used to manipulate non-semantic view trees.

 * (e.g. a view created from HTML string on paste).
 * To manipulate a view which was or is being downcasted from the the model use the
 * {@link module:engine/view/downcastwriter~ViewDowncastWriter downcast writer}.
 *
 * Read more about changing the view in the {@glink framework/architecture/editing-engine#changing-the-view Changing the view}
 * section of the {@glink framework/architecture/editing-engine Editing engine architecture} guide.
 *
 * Unlike `ViewDowncastWriter`, which is available in the {@link module:engine/view/view~EditingView#change `View#change()`} block,
 * `ViewUpcastWriter` can be created wherever you need it:
 *
 * ```ts

 * writer.appendChild( text, someViewElement );
