Calculator for determining directional Earth Movers Distance between distributions in .txt files from mass cytometric analysis

Earth Movers Distance (aka Wasserstein distance) is a way of describing the difference between two distributions.  It is a more accurate way of demonstrating differences in cytometric datasets than metrics such as delta-MFI, which neglect the single-cell nature of these datasets.

This version of the code is aimed at mass cytometric datasets, so includes an arcsinh transformation.

EMD is a non-directional measurement of difference, so the directionality is added by comparing the means of the datasets.  This can be changed to median or another metric if needed.
