/** 
The SMS client MTM interface.

Most of the functions in this class are implementations of the virtual functions 
defined by the base class CBaseMtm.

An object of this class can be obtained from the Client MTM registry. The message
server provides the necessary information required by the registry to provide
the SMS client MTM.

All client MTM objects have a current context. This is an entry in the message 
store that will be manipulated by certain APIs supplied by the MTM. If the 
current context is not set then certain APIs will panic. 

The CBaseMtm::HasContext API can be used to check that the current context has 
been set. It can be set using either the CBaseMtm::SwitchCurrenEntryL API or the
CBaseMtm::SetCurrentEntryL API.
