// Javascript helper functions for parsing and displaying UUIDs in the MongoDB shell.
// To create BinData values corresponding to the various driver encodings use:
// var s = "{00112233-4455-6677-8899-aabbccddeeff}";
// var uuid = UUID(s); // new Standard encoding
// var juuid = JUUID(s); // JavaLegacy encoding
// var csuuid = CSUUID(s); // CSharpLegacy encoding
// var pyuuid = PYUUID(s); // PythonLegacy encoding
// To convert the various BinData values back to human readable UUIDs use:
// uuid.toUUID() => 'UUID("00112233-4455-6677-8899-aabbccddeeff")'
// juuid.ToJUUID() => 'JUUID("00112233-4455-6677-8899-aabbccddeeff")'
// csuuid.ToCSUUID() => 'CSUUID("00112233-4455-6677-8899-aabbccddeeff")'
// pyuuid.ToPYUUID() => 'PYUUID("00112233-4455-6677-8899-aabbccddeeff")'
// With any of the UUID variants you can use toHexUUID to echo the raw BinData with subtype and hex string:
// uuid.toHexUUID() => 'HexData(4, "00112233-4455-6677-8899-aabbccddeeff")'
// juuid.toHexUUID() => 'HexData(3, "77665544-3322-1100-ffee-ddccbbaa9988")'
// csuuid.toHexUUID() => 'HexData(3, "33221100-5544-7766-8899-aabbccddeeff")'
// pyuuid.toHexUUID() => 'HexData(3, "00112233-4455-6677-8899-aabbccddeeff")'
