// Description:
// These methods should be used instead of the SwapBytes methods.
// They indicate the byte ordering of the file you are trying
// to read in. These methods will then either swap or not swap
// the bytes depending on the byte ordering of the machine it is
// being run on. For example, reading in a BigEndian file on a
// BigEndian machine will result in no swapping. Trying to read
// the same file on a LittleEndian machine will result in swapping.
// As a quick note most UNIX machines are BigEndian while PC's
// and VAX tend to be LittleEndian. So if the file you are reading
// in was generated on a VAX or PC, SetFileTypeLittleEndian otherwise
// SetFileTypeBigEndian.
