Use Native JS Modules #29

When this app was first created native JS modules were not well supported. It appears JS modules are now supported well enough to use. Historically JavaScript code has been organized by simply following developer enforced conventions, strategies, and patterns. We used the "Revealing Module Pattern" in WAVE. Other strategies of old include Immediately Invoked Function Expressions (IIFEs), Namespaces, Object Literals, and even custom module systems such as AMD and CommonJS.
