search results from codelets.

Add:
    templates/index.html
        -Simplify form layout: reduce the number of independent adjacent `div`s,
        and position `label`s above their corresponding `input` elements.

    static/sass/index.sass
        -Remove now superfluous positioning rules for the previous layout.

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

    app.py, templates/(about, developers).html
        -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.

Add:
    static/js/index.js
        -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
        downwards-cascading animation.

Add:
    static/sass/index.sass
        -Add a gradual CSS `transition` to the search-bar, when a query is
        entered for the first time.

    static/sass/_variables.sass
        -Add bitshift's three new primary base colors.

Add:
    static/js/index.js
        -Add conditional to prevent a search from being triggered when a
        non-character key combination (ie, `up`, `down`, `ctrl-c`) was entered.
        -Add `queryServer()`, currently only for testing purposes (it populates
        `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
        visible (in other words, at any point after a query has been executed).

Add:
    templates/index.html
        -Add search bar elements.

    static/sass/index.sass
        -Add styling for the search entry bar.

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
        -Add styling to the new footer, which is always floored to the bottom of
        the page (even when an otherwise insufficient amount of content is
        present).

Add:
    static/sass/main.sass
        -Complete `template/layout.html` positioning rules.
        -Add some styling to the footer.

    static/sass/_variables.sass
        -Add `SASS` partial to contain all project-wide variables.

		an HTML asset tag based on a filename.

	bitshift/config.py
		-add Flask configuration module.

	static/(sass/main.sass, css/main.css)
		-create isolated directory for SASS files; compiled CSS files will be
		stored in static/css.

		-add SASS partial to contain mixins (globally relevant to the project's
		styling).

		-add various metadata.
