/**
* Entry point to our rest-frontend of the Swissfel application which most importantly wires all the @RestController annotated classes.
* <p>
*
* This acts as a @Configuration class for Spring. As such it has @ComponentScan
* annotation that enables scanning for another Spring components in current
* package and its subpackages.
* <p>
* Another annotation is @EnableAutoConfiguration which tells Spring Boot to run
* autoconfiguration.
* <p>
* It also extends SpringBootServletInitializer which will configure Spring
* servlet for us, and overrides the configure() method to point to itself, so
* Spring can find the main configuration.
* <p>
* Finally, the main() method consists of single static call to
* SpringApplication.run().
* <p>
* Methods annotated with @Bean are Java beans that are
* container-managed, i.e. managed by Spring. Whenever there are @Autowire, @Inject
* or similar annotations found in the code (which is being scanned through the @ComponentScan
* annotation), the container then knows how to create those beans and inject
* them accordingly.
