// CLASS DECLARATION

/**
*  The basic client class.
*  The basic client class representing a channel of communication 
*  with the server. The connect function starts the server, if it 
*  is not already running. An RSessionBase sends messages to the 
*  server with the function RSessionBase::SendReceive(); specifying 
*  an opcode (TScardServerRqst) and and array of argument pointers. 
*  This class is a friend to the classes Comm and Listener.
*  All four are classes that need to communicate 
*  directly with the server.
*
*  @lib Scard.lib
