CIEDE2000计算实例，每个步骤都有，计算最新的色差公式-Ref: G. Sharma, W. Wu, E.N. Dalal,"THE CIEDE2000 COLOUR-DIFFERENCE FORMULA: Implementation Notes, Supplementary Test Data, and Mathematical Observations," submitted to COLOR RESEARCH AND APPLICATION, Jan 2004.

This function Compute the CIEDE2000 color-difference between the sample between a reference with CIELab coordinates Labsample and a standard with CIELab coordinates Labstd The function works on multiple standard and sample vectors too provided Lab
