\brief ClipAnimator is a component providing simple animation playback capabilities.
An instance of ClipAnimator can be aggregated by an Entity to add the ability to play back
animation clips and to apply the calculated animation values to properties of QObjects.
The animation key frame data is provided via the clip property. This can be created
programmatically with AnimationClip or loaded from file with AnimationClipLoader.
In order to apply the values played back from the channels of data in the animation clip, the
clip animator needs to have a ChannelMapper object assigned to the channelMapper property.
The properties for controlling the animator are provided by the AbstractClipAnimator base
class.
