  Fix Rec.709 ODT EOTF to correspond to recommendation in Appendix 1 of ITU-R BT.1886.
  Add regenerated V3 transforms (no semantic difference from prior transforms)
  Add regenerated V2 transforms (no semantic difference from prior transforms)
  Update idt_maker_script.csh to generate v2 and v3 trees; this time don't imply that v3 LogC is CCT-dependent. Update v2_IDT_maker.py and v3_IDT_maker.py to make them more robust in the face of mixed-case arguments, and update their version numbers. Update README to reflect lack of channel gain file, etc.
  Remove alexa_balance.txt, since the channel gains don't matter in IDTs (neither in raw nor in LogC IDTs). Clear out v2 and v3 transform directories; we are going to replenish them but with a new structure.
  Added images directory with README containing a link to FTP server where reference footage can be found.
  Added CHANGELOG Update ctlrender makefile to install rrt and utilities.
  Added CTL transforms.
  Updated apps/ctlrender/README.rst to reflect IIF to ACES name change.
  Updated License Language and README.rst
  Corrected a typo in the symbolic link to CtlManual.pdf.
  Updated README files to .rst format for better preview in github.com
  Added clip, min, and max functions to utilities.ctl.
  renamed directory
  Updated path in symbolic link to CtlManual.pdf
  Updated cltrender readme
  ctlrender cleanup

Closes #2
Closes #3
Closes #4

Patch provided by Jun Onuki (Sony Electronics)
Adds reverse of RRT and RDT splines. Slight tweaks to RDT coefficients modifying shadow reproduction.

Fix header formatting in p3d60 and p3dci ODTs.

Replace tabs with spaces so that alignment is consistent when previewing source on github.
adds support for SMPTE (legal) range output from odt_rec709.ctl

* keeps the default range from odt_rec709 as full range
* adds boolean flag 'smpteRangeOut' to allow for legal range output
* modifies utilities.ctl functions smpteRange_to_fullRange and fullRange_to_smpteRange from type void to type float[3]
* closes #19 (pull request)
adds documentation to clarify the white point handling methodology between OCES and device code values

* adds 'assumed observer adapted white point' in header comments of ODT transforms
* closes #20 (pull request)
replaces declared constant with function to calculate white point handling transform in ODTs

* adds xyY_to_XYZt to utilities
* adds calculate_cat_matrix to utilities
