/*
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   Personal Bio Utilities
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   These are the routines used on the Gavora Studio
   web-site to display and hide the divs for the girls'
   biographies, and to display fly-over tips.

   Note that these routines are here because they are
   generic, but they depend on a "hideAll" function that
   isn't, and it's defined in the index.php file.

   Likewise, the fly-over routines depend on the
   existence of a "divTipBox" div that defines, through
   its style settings, a small box.

   Collected together, tweaked, mashed, and polished by
   TGE Software.
