search results from codelets.

        -Remove now superfluous positioning rules for the previous layout.

        -Add new results to the results `div` whenever the user scrolls to the
        bottom of the page.

Add:
    static/js/index.js
        -Add `populateResults()`, to distinguish the addition of results to
        `div#results` from the retrieval of Codelets from the server itself.
        -Add `clearResults()` for convenience.

    static/sass/index.sass
        -Add `.cascade`, to provide new `div.result` elements with a

        non-character key combination (ie, `up`, `down`, `ctrl-c`) was entered.

        `div#results` with randomized content).
        -Add documentation comments to all functions.

    static/sass/index.sass
        -Add different styling to the `#search-field` whenever results are

Fix:
    static/sass/main.sass
        -Fix footer's styling, which lacked a `bottom: 0px` that floored it.

Add:
    templates/layout.html
        -Add `header`, `body`, and `footer` divs, for greater modularity and to
        floor the footer.

    static/sass/main.sass
