Merge pull request #64 from RedHatBrand/add-sass-helper-functions

Add sass helper functions

Thanks for this @castastrophe ,  I wasn't sure if this should live in the project repo or not, since many people seeking the webfont may not be using scss.  But, it's a way cleaner setup that I would have written,  super helpful for those who need it,  and not hard to trim-out either. 

Thanks a heap,
Merged!
