FourBytes(big: Byte, bigish: Byte, lowish: Byte, low: Byte, bigEndian: Boolean)
bigish - secondmost significant byte
lowish - thirdmost significant byte
bigEndian - true if the bytes should come in the order from most significant first
to least significant last, false if the order should be exactly in reverse
FourBytes(uintValue: UInt, bigEndian: Boolean)
Initialize a four byte sequence with a 32 bit unsigned integer, either as big-endian or little-endian.
uintValue - the 32 bit unsigned integer value
bigEndian - if true, the number is encoded in big-endian byte order, otherwise in little-endian
FourBytes(a: Byte, b: Byte, c: Byte, d: Byte)
Container class for four bytes, that can then be converted to a Long value, either as big endian or little endian.
