Hmm, should we maybe call the package lato-fonts or latofonts to find it easier when searching for fonts?

[chris-martin]

I'm not sure why the fonts aren't just under their own namespace e.g. fonts.lato in the same way that, say, pythonPackages are. I was just trying to follow the example of all the other font packages here.

Looks ok at the moment. The namespacing can be done as a separate issue.
