/**

 *  SMS Stack clients use specialisations of this class to configure a SMS Message with parameters which are not

 *  a type of Information Element.

 *

 *  Each parameter that uses this interface is supported by a class derived from CSmsNonIEOperation.

 *  The derived class operates on the CSmsMessage, allowing the client to add, remove and access these parameters

 *  inside the CSmsMessage.

 *

 *  The client gets access to an operations class using the following interface:

 *

 *  CSmsNonIEOperation& CSmsMessage::GetOperationsForNonIEL(TSmsNonIEIdentifier aId);

 *

 *  When the CSmsMessage is deleted, all its associated CSmsNonIEOperations classes are also deleted and references to

 *  them become stale. Each instance of the CSmsNonIEOperation Class is an attribute of the CSmsMessage itself.
