SetupAuth - Will enable authentication middleware if appropriate environment variables are set.For now, will always setup and will add future flags when needed to support on/off + diff authentication stylesThe assumption for all users as that this will setup the auth only, the determination of correct level of auth will be determined by the api functions themselves.

SetupCORS - Eables CORS Middleware.

SetupErrorHandler - Will setup last resort error handlerFor now, will always setup and will add future flags when needed to support on/offFor now I am not writing a speific http response here but that may be the right thing to do eventually.

SetUpMiddleware contains the middleware that applies to every request.
