+/**
+ * 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 {@link @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.
