Games:3D:

2003-03-02 v0.01 Tels - 166 tests (first version)
 * added Game::3D::Point, w/ 3D center
 * added Game::3D::Area, Point plus 3D size and shape
 * added Game::3D::Thingy, id, name, state, active/inactive, has outputs
   and can receive/send signals
 * added Game::3D::Signal, export the signal names
 * added Game::3D::Link to link two thingies together (in more complicated
     ways than just connecting the output from thingy #1 to thingy #2),
     features count, initial delay, resend delay, one-shot, invert, fixed
     output signal etc
 * added Game::3D::Physical, isa Area and Thingy, plus mass
 * added Game::3D::Living, a living thing (like NPCs etc)
 * added Game::3D::Marker, isa Point and a Thingy
 * added Game::3D::Trigger, isa Area and a Thingy

2003-03-06 v0.02 Tels - 181 tests
 added:
  * basic tests for Trigger.pm
  * Area: has rotation()
 fixed:
  * Game::3D::Point::center() renamed to pos()

2003-03-08 v0.03 Tels - 180 tests
 added:
  * Thingy: load() and _construct(), load hirarchy and objects from text file
  * example text-adventure game in ./examples showing class-hirarchy and level
    loading code
  * forgot to include trigger tests
 Caveat: Some classes like Trigger, Living, Marker, Physical etc might be gone
         from the next version, since they can be replaced by text-definitions
         in the object hierarchy, completely!

2004-02-29 v0.05 Tels - 73 tests

    parent Thingy
