Evaluate refactoring F2.js from singleton to fill-in-the-blank-javascript-pattern #29
Description
F2.js creates a singleton on the window and you can't create more than one instance of window.F2... which would allow n F2 containers within a single page. This issue can track our evaluation of changing the current pattern to something else—perhaps a JS pattern that more closely follows AMD, coupled with a simultaneous replacement of F2's internal dependency loader.
