    README -- Organization of Callback Functions

    In an effort to compartmentalize our development where possible, all callbacks directly relating
    to pages in our application are in their own files.

    For instance, this file contains the layout logic for the index page of our app-
    this page serves all other paths by providing the searchbar, page routing faculties,
    and data storage objects that the other pages in our app use.

    Having laid out the HTML-like organization of this page, we write the callbacks for this page in
    the neighbor 'app_callbacks.py' file.
