Regex for FORTRAN Throws an Error #398

When running lizard over a fortran file, I'm getting this error:

It looks like this is an issue with the regex that's attempting to pull methods or functions out of this file. I'm interested in taking a stab at fixing this, but I wanted to put this here for completeness.

Thanks for the report. It's fixed with the commit https://github.com/terryyin/lizard/commit/ff1928bd96607deb70396e268b6b54dbbe9967e7 please try again. Also I created a new release on pypi.
