Color Science - Calculate a MacAdam Ellipse Table

This is a simple program that takes a CIEx, CIEy color point coordinate and desired SDCM and outputs a table of CIEx, CIEy coordinates for the MacAdam ellipse centered on that point which can be pasted into Excel.

The method follows CIE TN 001:2014 "Chromaticity Difference Specification for Light Sources". The program takes the inputs (CIEx, CIEy, nSDCM) and converts to u',v'. It draws a circle in u'v' space and then converts back to CIE 1931 xy space to produce a set of ellipse points.
