- Added new ShapeVectorToy to showcase the basic ShapeVector object
- Fixed radius calculation when resizing circular ShapeVector objects
- Only call the "onExit" method if it exists.
- Added first pass of reference documentation generation.
- Relocated to the tools folder.
- Renamed the dOxygen configuration under Windows.
- Moved and renamed the "setTimerOn()" and "setTimerOff()" functionality from SceneObject to SimObject.  These are now named "startTimer()" and "stopTimer()" and now allow the callback function to be specified as well as the timer period and an optional repeat count which if not specified or specified as zero will repeat infinitely.
- Modified all the toys to use "startTimer()" as it's far less verbose than the ".schedule()" equivalent in these cases.
- Updated Win32 (VS2010/VS2012), OSX & iOS builds.
- MoveTo and Rotate to now both use a "speed" parameter rather than a "time" parameter.  This always caused people confusion and is used as speed by many.
- Modified the toys that use this including adding a "trackMouse" option to both "MoveTo" and "RotateTo" toys.
- The DeathBallToy needs looking at, it's not really optimized for T2D MIT yet.
- Corrected the VS2012 solution file (or should I say that VS2012 Express for Desktop corrected it) so that it opens correctly with the Visual Studio version selector.  If this causes problems with other versions of VS2012 then we'll need different variation folders but I hope not.
- Updated Doxygen to latest stock one for Win32.
- Tidy of script output.
- Some refinements to the navigation layout for the documentation.
- Removed obsolete entries in Doxygen configuration.
- Added a read-me for the documentation generation tools.
- Removed the OSX generate-docs command for now as it's not ready.
