Simple script for creating layered cumulative plots using T-HIS datums:

• When running this script the user selects a number of curves.
• The curves are sorted into descending order based on their peak values.
• Datums are created to give the appearance of the curves being layered on top of each other (largest at the bottom, smallest at the top).
• Datum colours are taken as curve colours and the user is asked whether they would like dummy curves to be created to create a legend (since using the original curves as the legend conflicts with the datum plot).
