Fixes, new ACES colorspaces, rgb_to_rgb_matrix

• Add ACEScg and ACEScc colorspaces
• Update ACESproxy colorspace
• Deprecate ACESlog colorspace
• Convert rgb_to_XYZ_matrix to rgb_to_rgb_matrix
• Add input_range for cube LUTs

Some work about matrices

• factorize some string functions
• add a primaries only option in rgb_to_xyz_matrix tool

Concatenate LUT and label correctly curves

LutLab

• Add curve labels in plot_that_lut
  
• Allow LUT concatenation in lut_to_lut

dev

• Some clean

Presets for lut_to_lut and curve_to_lut

LUTLab

• lut_to_lut and curve_to_lut can now use presets file to define export LUT settings.
  See some samples here
• ext_to_1d_lut has been merge into lut_to_lut. Say hello to --smooth-size option !
• curve_to_lut has now on option to auto-detect input range : --process-input-range

There's many changes on this tools, see readme.

Utils

• New helper : 3dl
• Improved helper : spi, cube, csp, ascii

Dev

• Lots of refactoring
• New tests (and a jenkins build).

v0.10

LutLab

• Add first version of plot_that_chroma, a command line tool to display xy / u'v' coords in CIE diagrams.
  Ex :
  
• Add Scratch 1D LUT support in curve_to_lut

utils

• Add Scratch 1D/2D LUT support

New features

LUTLab

• Add ACES colorspaces
• curve_to_lut : a command line tool to process a 1D LUT from a gradation function

Utils

• Helper functions to plot chromaticity coordinates in CIE1931 or CIE1976 diagrams

Web app

• CherryPy web app has been refactored to anticipate the integration of LUTLab tools (like lut_to_lut for example)

Minor features

• Add first functions to support spi, 3dl, clcc formats
• Add version number in the scripts and options to display these versions in cmd line tools

New features in LUTLab and PlotThatLUT

LUTLab

• Colorspaces definitions
• RGB to XYZ matrices generator
• 3D json export

PlotThatLut

• Possibility to display several curves

v0.5

Lut_to_lut 3d cube export and inversion options

v0.4

New features and scripts.
