// 10/31/2003 11:28PM
// Version Beta 2.2
// Added some contrast adjustments and re-wrote main randomizer code to
// work by category of "accident"
//
// 10/26/2003 9:19PM
// Version Beta 2.1
// Modifications made to library code.  This version now operates
// interactively only.
//
// 10/26/2003 0:28AM
// Version Beta 2
//
// 10/25/2003 11:34PM
// New build system to better manage code.
// Now applies PhotoKit effects in random order
// Combined PhotoKit and Tone betas into a single script.
//
// Version Beta 1, 10/25/03
// First beta release
