// DESCRIPTION OF THE SCRIPTS
//
// ~run:
//  Default: sets other scripts to not running.
//  When the object is touched it will start all scrips.
//
// ~memory:
//  Here the positions are stored permanently. Information is still kept when the script is
//  not running or when everything is placed in inventory. The information will be lost only
//  when the ~memory script is reset.
//  A backup can be made on the .POSITIONS notecard, when the memory is empty, it will start
//  reading the .POSITIONS notecard automatically.
//
// ~menu:
//  1.loading: reads the .MENUITEMS notecard and builds the menu.
//    When it reads a "POSE": - the animations are stored in ~pose
//                            - their matching positions are looked up in ~memory and stored
//                              in ~pos.
//  2.ready:
//    When the object is touched: - shows the main menu
//                                - listens for menu selections.
//
//    When a submenu is selected: - shows the submenu
//                                - when balls are defined for this submenu it will rez
//                                  balls (if not already there) and set their colors.
//
//    When a pose is selected:  - ~pose will send the animations to ~pose1 and ~pose2,
//                                 they will set the animations to the avatars
//                              - ~pos wil send the matching positions to each ball.
//
//    When a position is saved: - ~pose will ask the balls for their position
//                              -  the positions are saved in ~memory ("permanent")
//                              -  the positions are updated in ~pos
//                                  
//    When "STOP" is selected:  - will hide the balls
//                              - will stop the pose
//                              When "STOP" is selected again (or if no pose is started yet):
//                              - will remove the balls (derez/die)
//
// ~pos:
//  - loads the positions from ~memory and stores them (until shutdown/restart)
//  - sends positions for the selected pose to the balls
//
// ~pose:
//  - loads the animations from the .MENUITEMS notecard and stores them (until shutdown/restart)
//  - sends animations for the selected pose to ~pose1 and ~pose2
//  - when saving a position: will ask balls for their position and sends it to ~pos and ~memory
//    (~pos would be a more logical place to handle this, but ~pose has more free memory).
//
// ~poser, ~poser 1, ~poser 2, ~poser 3 (one for each ball):
//  - will ask permission to animate the avatar on ball
//  - will set the animations to avatar
//
// ~ball
//  - when balls are defined for a submenu (in .MENUITEMS), ~menu will rez copies of ~ball
//  - each will receive a unique communication channel from ~menu
//  - the color for each ball is set by ~menu
//  - the position of each ball is set by ~pos
//  - when an avatar selects to sit on a ball, the avatar info is sent to the appropriate; they
//    will ask permission and set the animation directly to the avatar (not via the ball)
//  - balls will commit suicide when they don't hear a "LIVE" message each minute (from ~menu).
//
// have fun!
