Include test/example case #3
Description
I have tested this using an example RCP8.5 run, and produced the same plot as Ashly Spevacek who was running Yen-Ting Hwang's original code, which is how I know the Python version works. But I don't want to upload the original CMIP5 output files. I may provide an example script with a blank path to output, and state where to download the output files.
