/*C+ TTYDisplay
*
*    DESCRIPTION:
*
*    The class provides such terminal emulation capability as a TTY 
*    subwindow, which is like having a shell tool available. An application 
*    can be run or an interactive shell can be started.  This class uses
*    the XView TTY package (as opposed to using the TERMSW package).
*
*    INHERITED CLASSES:
*
*    UIDisplay - Supplies basic display capabilities.
*
*    ORDINARY DATA MEMBERS:
*
*    Boolean fdToSTDIO - Specifies whether or not the TTY file descriptor
*                        should be set to STDIN and STDOUT.
*    char **ttyArgs - Pointer to the parameters that define the terminal.
*
*    ORDINARY MEMBER FUNCTIONS:
*
*    void setFDToSTDIO - Sets the TTY FD to STDIN and STDOUT.
*
*    PROTECTED MEMBER FUNCTIONS:
*
*    virtual void        createDragSite () - Creates a drag site for this
*            object.
*
*    virtual void        createDropSite () - Creates a drop site for this
*            object.
*
*    virtual void createObject (UIObject *) - Creates the XView object.
