Go where I'm looking

In this next script, instead of being random, we'll send Ethan to wherever we look. In Unity, this is accomplished by using ray casting—like shooting a ray from the camera and seeing what it hits (for more information, visit http://docs.unity3d.com/Manual/CameraRays.html).

We're going to create a new script, which will be attached to WalkTarget like before, as follows:
