look at the css stuff in pygments
modules should now return a RenderedResult
Merge branch 'feature/refactor' of https://github.com/asmacdo/modular-file-renderer into feature/refactor
Modified mfr_ipynb and mfr_image to work with RenderedResult. Also made a small addition to views.py so that it doesn't automatically crash if the module doesn't send any css.
