-// class TimeCode
-//
-// A TimeCode object stores time and control codes as described
-// in SMPTE standard 12M-1999. A TimeCode object contains the
-// following fields:
-//
-// Time Address:
-//
-// hours integer, range 0 - 23
-// minutes integer, range 0 - 59
-// seconds integer, range 0 - 59
-// frame integer, range 0 - 29
-//
-// Flags:
-//
-// drop frame flag boolean
-// color frame flag boolean
-// field/phase flag boolean
-// bgf0 boolean
-// bgf1 boolean
-// bgf2 boolean
-//
-// Binary groups for user-defined data and control codes:
-//
-// binary group 1 integer, range 0 - 15
-// binary group 2 integer, range 0 - 15
-// ...
-// binary group 8 integer, range 0 - 15
-//
-// Class TimeCode contains methods to convert between the fields
-// listed above and a more compact representation where the fields
-// are packed into two unsigned 32-bit integers. In the packed
-// integer representations, bit 0 is the least significant bit,
-// and bit 31 is the most significant bit of the integer value.
-//
-// The time address and flags fields can be packed in three
-// different ways:
-//
-// bits packing for packing for packing for
-// 24-frame 60-field 50-field
-// film television television
-//
-// 0 - 3 frame units frame units frame units
-// 4 - 5 frame tens frame tens frame tens
-// 6 unused, set to 0 drop frame flag unused, set to 0
-// 7 unused, set to 0 color frame flag color frame flag
-// 8 - 11 seconds units seconds units seconds units
-// 12 - 14 seconds tens seconds tens seconds tens
-// 15 phase flag field/phase flag bgf0
-// 16 - 19 minutes units minutes units minutes units
-// 20 - 22 minutes tens minutes tens minutes tens
-// 23 bgf0 bgf0 bgf2
-// 24 - 27 hours units hours units hours units
-// 28 - 29 hours tens hours tens hours tens
-// 30 bgf1 bgf1 bgf1
-// 31 bgf2 bgf2 field/phase flag
-//
-// User-defined data and control codes are packed as follows:
-//
-// bits field
-//
-// 0 - 3 binary group 1
-// 4 - 7 binary group 2
-// 8 - 11 binary group 3
-// 12 - 15 binary group 4
-// 16 - 19 binary group 5
-// 20 - 23 binary group 6
-// 24 - 27 binary group 7
-// 28 - 31 binary group 8
