/*
 * 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.
