Version 0.6.0 (Sept 21 2010):
* Start of 0.6, "stable" branch

All 0.6.x builds will be ABI compatible (forward only).
New features (even experimental ones) will be added to the 0.6
branch,
as long as binary and source compatibility is maintained.
Once this no longer is possible, a 0.7 "dev" branch will be
forked.

* Split public header into 3 parts for improved readability
(you still only import <OpenColorIO/OpenColorIO.h> though)
* Added MatrixTransform
* Refactored internal unit testing
* Fixed many compile warnings
