 @brief    A table header cell that is a popup menu!

 @details  This class is based on Keith Blount's original work
 http://www.cocoabuilder.com/archive/message/cocoa/2005/4/16/133285
 or http://lists.apple.com/archives/cocoa-dev/2005/Apr/msg01223.html
 but I've made enough improvements to it that I decided it deserves
 to have my own SSY prefix.

 @brief    If not nil, the receiver behaves like a plain table header cell,
 with no popup menu, but with a blue/black sort control, to match the
 blue/black sort control of SSYPopUpTableHeaderCell that have popup menus.
 
 @details  Set this if you have a column in a table of user-defined popup
 columns which you do *not* want to have a user-definfed popup menu.
