Divided Sass into multiple files

Used "@import" to pull all stylesheets into one 1 CSS document. New
Sass stylesheets are divided up by section or characteristic, and any
new 3rd-party CSS (like the HTML5Doctor reset), will be labeled as
3rd-party in the global.sass file.
Attempting another push from new local repo.
Found way to add green stripe to header using an 'inner-border' class with 'inner-border: before'. Also added inner-shadow mixins, but for some reason, the  argument of 0 isn't recognized.
Solved the  argument problem with my inner-shadow mixins: When I write the @include part, I have to enter a comma after each variable within the parentheses. Otherwise, Sass thinks that all of those entries are for 1 value rather than for all 5.
