/** A cell view that shows the daytime demo clock, using a scene flob.
 *  For use with ideosyncratic cell view. Create the cell to be shown as a
 *  clock. Posward on d.3, connect the clock cell to a d.2 rank of appointments
 *  in the regular DayTimeDemo structure (see DayTimeDemo.zob and the
 *  CyberText article pictures). Then, from the clock cell negwards on
 *  d.cellview create a new cell and write the cell view's name, e.g.
 *  "Clock Cellview," in it. From that cell, create a new cell poswards on d.1
 *  and write "DayTimeDemo.C" (of course w/o quotes) in it. Use F2 to switch
 *  to the ideosyncratic cell view, and the clock cell should change its
 *  appereance to a DayTimeDemo clock. (Best viewed with StretchVanishing or
 *  Quad view, so that it's not shown that small.)
