Leap Motion + Unity 5 + Oculus Hand debugging script

    // Attach this script to any game object in your scene. I have an empty GameObject named "GlobalScripts" 
    // that I attach these kinds of "global" scripts to, but anywhere should work.
    //
    // Once this script is in your scene, select the game object the script is attached to in Unity's 
    // Inspector panel (the panel that's usually on the right hand side of Unity's main window). When you 
    // see "Oculus Rig" and a box that reads "None (GameObject)", you'll be looking at the right place.
    //
    // Now, assuming you've already got a LMHeadMountedRig object in your scene, you should be able to click
    // on it in the Hierarchy panel on the left hand side of Unity and drag-and-drop it into the box named
    // "Oculus Rig"
    //
    // Now, click on the "Game" tab, find the "Gizmos" drop down at the top of the Game tab, and click on it
    // to enable Gizmos in the game view.
    //
    // Run your scene, put your HMD on, and wave your hands around in front of your face.
    //
    // You should see a bunch of rays coming out of your hands!
    //
    // Oh, and select "VR_WORLD_AR_HANDS" from the drop down in the LMHeadMountedRig object while you're 
    // messing around. Those hands operate a lot more smoothly in some situations...
