//  Procedure Name:
//
//      reverseKeys;
//
//  Description:
//	This simple script reverses keyframes of all objects below in a heiarchy
//	Be careful when using this script with objects with any set driven Keys
//	because it will reverse them as well.
//
//  Usage:
//	user must enter the first and last of the frames to be scaled
//	usually this will be the last keyframe of the objects selected.
//	eg.	reverseKeys(1,200);
//
//  Limitations:
//	any keyframes outside the range of keyframes entered will not be scaled
//	and could result in unpredictable animation behavior.  Best when used with
//	an entire range of keyframes.
//
