// 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
//
