/**
* 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.
