added script (currently broken) to regenerate csv file of comparator homogeneity data files, for homogeneity figure.
Recreated the script to parse .npy files produced by homogeneity test scripts, output one DataFrame (containing all comparator models data) into one .csv
Reconfigured the ggplot / dplyr script to read from one file for comparator models, one file for SdA models, and use a new colour scheme for the homogeneity line plot.
