    Description: The CVolume class maintains information about a particular
        disk volume.  During initialization, the object determines if the
        associated volume supports quotas.  The object's client can then query
        it for volume-specific quota information.  Objects of this class are used
        in the CStatistics class to store information about a user/volume
        pair.
