/**
 * A base Guice module for creating a {@link CamelContext} leaving it up to the users module
 * to bind a Set<Routes> for the routing rules.
 * <p>
 * To bind the routes you should create a provider method annotated with @Provides and returning Set<Routes> such as
 * <code><pre>
 * public class MyModule extends CamelModule {
 *   @Provides
 *   Set<Routes> routes(Injector injector) { ... }
 * }
 * </pre></code>
 * If you wish to bind all of the bound {@link org.apache.camel.RoutesBuilder} implementations available - maybe with some filter applied - then
 * please use the {@link org.apache.camel.guice.CamelModuleWithMatchingRoutes}.
 * <p>
 * Otherwise if you wish to list all of the classes of the {@link org.apache.camel.RoutesBuilder} implementations then use the
 * {@link org.apache.camel.guice.CamelModuleWithRouteTypes} module instead.
