Adds, modifies or removes an object reference curve in a given clip.
Unity has two types of animation: Float and object reference. Float curve is a classic curve that animates float property over time. Object reference "curve" is a construct that animates object reference property over time.
This method is used for float curves. For object reference curves, see: AnimationUtility.SetObjectReferenceCurve.
