CMYKtoPMS.js
This script compares the color values of the selected CMYK object with built-in list of PMS solid colors and return closest match(es).
Compare based on cumulative values (C+M+Y+K), so PMS color with minimum color divergence is always selected. If the colors are also different, multiple matches will be displayed.
If no object is selected, or the wrong object type is selected, the user is prompted to enter the CMYK values manually.
