Add:
        static/(sass/about.sass, js/about.js)
                -Convert `adjustVimeoDimensions()`, which created the
                fluid-dimensioned Vimeo video, to a pure CSS solution.

Add:
        templates/about.html. static/(sass/about.sass, js/about.js)
                -Embed our Vimeo video, and add the Javascript necessary to make
                it fluid-width.

        templates/about.html
                -The file's indented formatting was completely mangled in a
                previous commit; reformat.

Add:
        templates/about.html
                -Replace filler text with real biographies.

Add:
        templates/about.html, static/sass/about.sass
                -Change parallax image offsets and scroll speeds; current
                implementation still isn't scalable to different resolutions
                (it'll work for most, but not all).

Add:
        templates/about.html, static/sass/about.sass
                -Add biography-section HTML structure and styling, containing
                filler images and lorem ipsum; now, it's just a matter of
                substituting in the appropriate content.

        static/img/about.bio(1, 2, 3).jpg
                -Add placeholder bio images.

Add:
        templates/about.html, static/sass/about.sass
                -Add text to the about page, and the necessary styling for it.

        app.py, templates/layout.html
                -Add an automated copyright year loader.

Add:
        templates/about.html, static/js/about.js
                -Add a `speed` attribute to all image divs, which is used to
                determine the rate at which an image moves upward.

        static/img/about/bg2.png
                -Change image to another source-code screenshot.

Add:
        static/sass/about.sass
                -Clean up existing style rules.
                -Add rules for the about sections' text.

        templates/about.html
                -Integrate with `templates/layout.html`, the project's global
                HTML template.

Add:
        templates/index.html, static/(sass/about.sass, js/about.js, img/about/)
                -Add first iteration of the about page, with basic parallax
                scrolling and filler text.

Add:
    templates/index.html
        -Add compartmental `div` structure for the advanced-search form.

    static/sass/index.sass
        -Add layout style rules to the advanced-search form.

        -Add `Flask` routes and skeleton files for pages to be developed later.

Ref:
    static/js/index.js
        -Substitute some verbose `JavaScript` calls with their `jQuery`
        equivalents.
