allow for application to be brought in as a dependency

[bdolor]

Is your feature request related to a problem? Please describe.
Since the front end of this application is loosely coupled, it will be relatively easy to access the application's functionality and pass the responsibility of look and feel over to a theme instead of having to rely on the application for look and feel concerns.

Describe the solution you'd like
I'd like to be able to composer install BCcampus/opentextbooks

• configuration options currently rely on a .env.somedomain.php file - I'd like to be able to introduce another way to set up the config that doesn't rely on a file that would get overwritten with each composer up

Describe alternatives you've considered
Currently we can iframe the application inside WP pages, which works, keeps the two separate, but is not ideal for a number of reasons.

Additional context
As a developer of a wordpress theme
I would like to be able to pull this application in as a dependency of my theme
So that I can access all its functionality and not be bound to iframing the existing 'views' currently available

[bdolor]

Note: though it would still be desirable to pull this in as a dependency, it has been designed to be a stand alone application and will require more time than is available in the current sprint to refactor. Keeping this as a standalone also benefits use cases where this application is used outside open-sage theme (i.e. Manitoba & Ontario)

Ok. What are the next steps for this one, @bdolor?

if entering a search term in the search component on the homepage takes you to the application (which displays all textbooks) then validation is complete.

Ok, perfect.
