   @brief Class used to specify what sub-system given sections of code belong

      to, for use by the logging system.

   @note The logging macros defined in Logger.hxx assume that the preprocessor

      macro RESIPROCATE_SUBSYSTEM is defined to an instance of this class. The

      logging macro uses this object to determine what logging level should be

      used, and what sub-system the logging statement should come from. So, in

      your code you might do something like the following:

      @code

      #define RESIPROCATE_SUBSYSTEM Subsystem::APP

      //...

      void doStuff()

      {

         DebugLog(<< "Doing some stuff...");

      }

      @endcode

      This would cause your log statement to be marked as coming from 

      Subsystem::APP.
