 class SwitchPathInterpolator
extends FloatValueInterpolator

This class was used in conjunction with SequenceReader to create Tloop functionality inside of Lightwave files. This behavior handles the switching between objects defined in separate lines of a sequence file. That is, each line in a sequence file has the name of an object (or an object sequence, if the name ends in "000") and details the start and end frames that that object should be active. This class determines which object/s defined in the file should be active at any given time during the animation.
