!! Using ActionSetFieldWidget and ActionListopsWidget

The widgets ActionSetFieldWidget and ActionListopsWidget can manipulate named properties of data tiddlers by indicating the name of the property in the $index attribute.

* To create or modify a named property with ActionSetFieldWidget, provide a $value attribute
* To delete a named property with ActionSetFieldWidget, omit the $value attribute.

ActionListopsWidget assigns the named property the list constructed through its $filter and $subfilter attributes.
