/**

Encapsulates functionality to set the Requested and Minimum Quality of Service 

options for a particular context (or "service configuration" in CDMA parlance), 

as represented by the RPacketContext class.

Methods are available to set and get the QoS options, query the QoS capabilities 

of the network service and notify the client if a change in the negotiated QoS 

options occurs.

A client must first create an instance of RPacketContext before opening a new 

RPacketQoS, since when creating a new RPacketQoS, the client must call the 

RPacketQoS::OpenNewQoS() function and pass in a reference to an RPacketContext 

instance.
