  DESCRIPTION OF CHANGE........................

  09/17/2003 Greg Basler                       CIGI_CR_DR_1
  Initial Release.

  01/21/2005 Greg Basler                       Version 1.5
  Added function modifiers to export the CigiSwap2, CigiSwap4, and CigiSwap8 
  functions when built as a Windows DLL.

  01/21/2005 Greg Basler                       Version 1.5
  Changed the implementations of the CigiCopy2, CigiCopy4, CIGI_FLOAT_TO_B6, 
  and CIGI_FLOAT_TO_BA to use CIGI-defined types instead of native C++ types.

  04/06/2005 Greg Basler                       Version 1.5.2
  Included the CigiTypes.h header file. Modified the CigiCopy2 and CigiCopy4 
  macros to use the cigi-defined data types instead of native types.

  06/23/2006 Greg Basler                       Version 1.7.1
  Changed native char and unsigned char types to CIGI types Cigi_int8 and 
  Cigi_uint8.

  11/20/2007 Greg Basler                       Version 2.0.0
  Changed CigiCopy8 to make sure that it works for big endian and non-intel
  machines.
