//	class KeyCode
// 	
// 	A KeyCode object uniquely identifies a motion picture film frame.
// 	The following fields specifiy film manufacturer, film type, film
// 	roll and the frame's position within the roll:
//
//	    filmMfcCode		film manufacturer code
//				range: 0 - 99
//
//	    filmType		film type code
// 				range: 0 - 99
//
//	    prefix		prefix to identify film roll
// 				range: 0 - 999999
//
//	    count		count, increments once every perfsPerCount
// 				perforations (see below)
// 				range: 0 - 9999
//
//	    perfOffset		offset of frame, in perforations from
// 				zero-frame reference mark
// 				range: 0 - 119
//
//	    perfsPerFrame	number of perforations per frame 
// 				range: 1 - 15
//
//				typical values:
//
//				    1 for 16mm film
//				    3, 4, or 8 for 35mm film
//				    5, 8 or 15 for 65mm film
//
//	    perfsPerCount	number of perforations per count 
// 				range: 20 - 120
//
//				typical values:
//
//				    20 for 16mm film
//				    64 for 35mm film
//				    80 or 120 for 65mm film
//
// 	For more information about the interpretation of those fields see
// 	the following standards and recommended practice publications:

// 			Latent Image Identification Information
