class PHASEEnvelopeSegmentOverview
This class specifies a curve that determines the _y-_value rate of change over a particular portion of an envelope’s graph. For example, the difference between a PHASECurveType.cubed segment and an PHASECurveType.inverseCubed segment is that they share opposite rates of change; where the cubed curve’s y value changes fastest in the segment’s domain, the inverse-cubed curve changes slowest, and vice versa.
