/**
* Wrapper around Gilead's LightEntity annotated properly to allow it to be serialized to JSON using Jackson.
*
* Jackson 1.6 throws an exception if it tries to serialize an object to JSON which contains a direct reference to
* itself. (That feature is intended as inexpensive protection against cyclical graphs; although it would be nice if we
* could tell Jackson to simply throw the field away instead of throw an exception.) Gilead 1.3.2 has a property on
* LightEntity called underlyingValue which is a direct reference back to the object itself. Thus any class derived from
* LightEntity cannot be serialized to JSON with Jackson. However, it is possible to annotate a class to tell Jackson to
* ignore certain properties; that is done here to tell Jackson to ignore the troublesome underlyingValue.
