Fix:
        templates/docs.html
                -Remove gap between the line-number column and code-viewport
                boundary in the API usage sample.

Add:
        static/sass/_logo.sass
                -The `bitshift` logo visible on our home-page may likely end up on
                other pages; move all of its styling to a SASS partial.

        templates/docs.html
                -Add `bitshift` logo.

Add:
        templates/docs.html
                -Reorganize page structure into a nested-unordered-list tree,
                for the inherent indentation.
                -Add content to each section.

        static/sass/docs.sass
                -Add virtually all of the necessary styling for the docs page.

Add:
        templates/docs.html
                -Add a skeleton structure for the documentation page.
                -Add some content to certain sections.
