     * Constructs an Import. An Import is a line in a JS file that imports a

     *
     *  - "page" is a page name, such as "User:Foo/Bar.js".
     *  - "wiki" is a wiki from which the script is loaded, such as
     *    "en.wikipedia". If null, the script is local, on the user's
     *    wiki.
     *  - "url" is a URL that can be passed into mw.loader.load.
     *  - "target" is the title of the user subpage where the script is,
     *    without the .js ending: for example, "common".
     *  - "disabled" is whether this import is commented out.
     *  - "type" is 0 if local, 1 if remotely loaded, and 2 if URL.
     *
     * EXACTLY one of "page" or "url" are null for every Import. This
     * constructor should not be used directly; use the factory
     * functions (Import.ofLocal, Import.ofUrl, Import.fromJs) instead.
