diff.py

#Reads two output files from shuffleparser and prints any differences between corresponding entries
#Usage: python diff.py input1 input2
#The input files are expected to use the format that is outputted by shuffleparser.py
#Namely:
#- Two line breaks (\n) between entries
#- First line of an entry is the index (which is ignored)
#- The rest of the lines of an entry will be of the format valuename: value
#It's also assumed that entries in the two files will be in the same order (meaning it doesn't check if the indexes are the same... for now)
#This has only been tested with Pokemon, Stage, and Ability data
