Use a Leap Motion

Hi all!

I try to use a Leap Motion. I downloaded the lastest version Torque 3D 3.5. I read "Using the Leap Motion Controller Input Events" (github.com/GarageGames/Torque3D/wiki/Using-the-Leap-Motion-Controller-Input-Even...) but I cannot find a word "leap" in the engine. David W. said in the document mentioned above that in the engine there are files platform/input/leapMotion/leapMotionConstants.h, platform/input/leapMotion/leapMotionFrame.cpp. I see there is no a folder "leapMotion".

May be Leap Motion support is not in a Master branch of code?
Where is it?

Thank you!
