How to allow a 3rd person character to face where the mouse is aiming

For future readers, the additions that he made (Break Rot and Make Rot) are isolating the Yaw, which is the angle on the X,Y plane (Pitch is for the Z plane, while Roll is not used). This makes sure that the character is looking parallel to the ground, while keeping the surface direction intact. This is perfect for Top-Down Shooters. For a Sidescroller, you would want to isolate the Pitch, although you would need to figure out the Yaw for the direction that you want to face (left or right).
