*
* LightObject is the highest level base class for most igtl objects. It
* implements reference counting and the API for object printing.
* It can be used as a lightweight base class in preference to Object.
* (LightObject does not support callbacks or modified time as Object
* does.) All IGTL objects should be a subclass of LightObject or Object
* with few exceptions (due to performance concerns).
