-The CameraEyeUnit is the unit whose point of view that the player's camera is going to try to portray. Think of it as the eyes the player is going to be looking through

-The CameraTargetUnit is a leftover from an earlier attempt at a First Person camera. It is not neseccary for the functioning of the camera. However, I am leaving it in because it may prove useful to future map makers as an aiming sight target or merely as a unit for the CameraEyeUnit's head to follow around (so it looks like the unit is looking up, down, whatever).

-step_backward is how far back the CameraEyeUnit will travel when the down arrow button is pressed

-step_foward is how far foward the CameraEyeUnit will travel when the down arrow button is pressed

-turning_angle is how much the CameraEyeUnit will turn when the side arrow buttons are pressed

-Source_Eye_distance is how far behind the CameraEyeUnit the camera source should be, measured from the center of the units selection center. This determines how much of CameraEyeUnit show up on a players screen. 70 works well for a normal sized rifleman.

-Eye_Target_distance is how far (minimally) in front of the CameraEyeUnit the Camera Target should be, measured from the center of the CameraEyeUnit's selection circle. Should be as small as possible for good camera motion. However Source_Eye_distance + Eye_Target_distance should be more than or equal to 100, since 100 is the minimum camera source to camera target distance set by Blizzard.

-EyeLevel is the z height above the ground you want the camera to be at. It should be set at the unit's eye level if it were standing on the ground.
