Cohen's Kappa (with customizable weightings)

A script to calculate Cohen's Kappa with the ability to do customizable weightings.

Description

This script is entirely and completely based on the previously published Cohen's Kappa script by Giuseppe Cardillo, available here:
http://www.mathworks.com/matlabcentral/fileexchange/15365

His script allowed you to calculate unweighted, linearly weighted, and quadratically weighted Cohen's Kappa. All that I have done is allow you to enter in a custom weighting matrix for use if your weights are not linear or quadratic.
