/**
 * A widget to display a value from an entry
 *
 * Since we have Etemplate\Widget\Transformer, this client side widget exists
 * mostly to resolve the problem where the ID for the entry widget is the same
 * as the widget where you actually set the value, which prevents transformer
 * from working.
 *
 * Server side will find the associated entry, and load it into ~<entry_id> to
 * avoid overwriting the widget with id="entry_id".  This widget will reverse
 * that, and the modifications from transformer will be applied.
