   This class represents the entire Wimpy Shell. An
   instance of this class is essentially an entire
   shell. It's only public method is to start the main
   control loop of the shell.
   
   NOTE: There is a maximum limit on the number of
         characters that are supported for the current
         working directory (CWD). Extremely nested
         folders will probably break this shell.
