+ * A ChainablePropertySet has the following features:
+ *
+ * 1. It implements both the PropertySet and MultiPropertySet interfaces.
+ * 2. It can be 'included' in a MasterPropertySet to seamlessly appear as if
+ *    if it's properties were in the master.
+ *
+ * To be used as a base class for PropertySets, the subclass must implement
+ * the 6 protected pure virtual functions. If a mutex is passed to the
+ * constructor, this is locked before any call to _getSingleValue or
+ * _setSingleValue and released after all processing has completed
+ * (including _postSetValues or _postGetValues )
+ *
+ * Any MasterPropertySet implementations that can include an
+ * implementation of a given ChainablePropertySet must be
+ * declared as a 'friend' in the implementation of the ChainablePropertySet.
