//**********************************
//RCountServSession
//**********************************

// Our client-side handle to a session with the server.
// The class forms a layer over the Symbian provided RSessionBase class.
//
// The class deals with the requests made by the main example code by forwarding
// them to the server. The type of request is identified by a code, one of
// the TCountServRqst enum values, and arguments are passed via a TIpcArgs object.
//
// The functions Increase(), Decrease() etc are wrappers for different calls to 
// SendReceive().
//
// Most of the functions here return void; if they fail, the server panics the client.
// If they return it can be assumed that there is no error.
//
// The RThread object is a handle to the thread that is acting as the server.
