Add files via upload

for bad input, changed the delimiters in the output to tab: from "-1,-1,-1" to "-1\f -1\t -1"

something is wrong about this pull request cause it is trying to add a new file instead of changing the existing mcz.py

instead of uploading from the inteface directly on my version of pymcz push a committ from your laptop

git commit mcz.py -m 'modifying output on error'
git push mcz.py 

you shoudl push to your fork, then submit a pull request from your fork. dont forget to pull before you push!
