Added three input/tableaux files which are superficial variants of
toy_input_3.txt. 'breaker0.txt' actually is the same so you can verify
I didn't do anything too cheaty. 'breaker1.txt' and 'breaker2.txt' break
the code in ways that are less alarming (breaker1) and more alarming.
Merge branch 'master' of https://github.com/rdaland/PhoMEnt
I have no fucking idea why this merge is necessary, since all I am doing
is adding files.
