/**
 * 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.
