*  DESCRIPTION
*  The main purpose of this script is to power a button prim that sits on the edge of a hexagon quizzer's pie slice.  A user can request that a 
*  new hexagon be joined to this edge by clicking on the horizontal rod, or vertical rod
*  When the horizontal rod or vertical rod is touched, this script will send a linked message to the hexagon rezzer script telling
*  it who touched
*  it.  It will also set the prims properties so that the orb reshapes itself small enough to be hidden (close) when needed.
