/**
 * This class allows us to isolate all our logging dependencies in one place. It also allows us to have zero runtime
 * 3rd party logging jar dependencies, since we default to JUL by default.
 * 
 * By default logging will occur using JUL (Java-Util-Logging). The logging configuration file (logging.properties)
 * used by JUL will taken from the default logging.properties in the JDK installation if no {@code  java.util.logging.config.file} system
 * property is set.
 * 
 * If you would prefer to use Log4J or SLF4J instead of JUL then you can set a system property called
 * {@code vertx.logger-delegate-factory-class-name} to the class name of the delegate for your logging system.
 * For Log4J the value is {@code io.vertx.core.logging.Log4jLogDelegateFactory}, for SLF4J the value
 * is {@code io.vertx.core.logging.SLF4JLogDelegateFactory}. You will need to ensure whatever jar files
 * required by your favourite log framework are on your classpath.
