Main
----

* Main module is executed when the CLI argument "bokeh serve <appDir>" is called.
* Primary function is to instantiate the:
    - `main` data source objects
    - content class objects added to the DOM within the jinja
* These objects produce the original "View" the user sees when visiting the dashboard
