more work on the ndof system.

turntable code should work reasonabilly well now.
fly code need works but is no more insane on Os X.
transform object is not present here.

if you find the movements a bit slow, you can speed
it in the preferences up to 2x in the view & controls
panel.

button1 (left) of the device let you switch between
the 3 modes. button2 let you switch between 
unconstrained and dominant mode.

the plugin must be named 3DxNdofBlender.plug
and be placed in a folder named plugins in same
folder as executable

check no scaling is done in the plugin

please check it works ok on 3 platforms
