<dt>Description</dt>
<dd>Base class to implement an UNO object supporting weak references, i.e. the object can be held
weakly (by a ::com::sun::star::uno::WeakReference) and aggregation, i.e. the object can be
aggregated by another (delegator).
This implementation copes with reference counting. Upon last release(), the virtual dtor
is called.
</dd>
<dt>How to Derive from this Class</dt>
<dd>
Inherit from this class and delegate acquire()/ release() calls. Re-implement
XAggregation::queryInterface().
