Ensures SASS modules can only be included once per build
When included in a Sass module, sass-import-once will prevent the styles being duplicated if
@importis called somewhere else. This is cool because it allows every Sass file to declare its own dependencies. This promotes encapulation and allows modules to standalone if need be.
$ component install wilsonpage/sass-import-once
$ bower install sass-import-once
Just copy the .scss file somewhere into your project.
