Broken file is Broken

[kajuberdut]

Using notepad to create a new text file on Windows causes errors when running thinkgraph on said file.

Example:
break.txt

C:\Users\pshec\Downloads\thinkgraph-master>thinkgraph break.txt

It appears to be related to windows line endings, I'm not sure exactly how to fix this, probably something to do with how grako is configured. I would've hoped that it would use the universal new line feature of Python's regexes, but apparently not.

[ryanfreckleton]

Well, a simple regex fix fixes it. :)
