-/**
- * TODO: Revisit for better Ardor3D integration.
- *
- * Started Date: Jun 12, 2004 <br>
- *
- *
- * Class can do linear interpolation of a Mesh between units of time. Similar to VertexKeyframeController but
- * interpolates float units of time instead of integer key frames.
- *
- * setSpeed(float) sets a speed relative to the defined speed. For example, the default is 1. A speed of 2 would run
- * twice as fast and a speed of .5 would run half as fast
- *
- * setMinTime(float) and setMaxTime(float) both define the bounds that KeyframeController should follow. It is the
- * programmer's responsibility to make sure that the MinTime and MaxTime are within the span of the defined setKeyframe
- *
- * Controller functions RepeatType and isActive are both defined in their default way for KeyframeController
- *
- * When this controller is saved/loaded to XML format, it assumes that the mesh it morphs is the Mesh it belongs to, so
- * it is recommended to only attach this controller to the Mesh it animates.
- *
- * (Based on work by Jack Lindamood, kevglass (parts), hevee (blend time), Julien Gouesse (port to Ardor3D))
