The JavaScript UI Language (JUL) is a configuration and instantiation module
for the JavaScript frameworks.
It can be used with any framework that accepts a configuration object
as a constructor parameter, or with a custom factory for the other frameworks.
JUL parses a tree of configuration objects, and creates the runtime components in the expected order and membership. For the most uses, after this step, you will have your application's user interface up and running.
