/**
 * Causes lombok to generate a logger field.
 * Example:
 * <pre>
 * &#64;Log
 * public class LogExample {
 * }
 * </pre>
 * 
 * will generate:
 * 
 * <pre>
 * public class LogExample {
 *     private static final org.apache.log4j.Logger log = org.apache.log4j.Logger.getLogger(LogExample.class);
 * }
 * </pre>
 * 
 * If you do not want to use the annotated class as the logger parameter, you can specify an alternate class.
 * Example:
 * <pre>
 * &#64;Log(java.util.List.class)
 * public class LogExample {
 * }
 * </pre>
 * 
 * will generate:
 * 
 * <pre>
 * public class LogExample {
 *     private static final org.apache.log4j.Logger log = org.apache.log4j.Logger.getLogger(java.util.List.class);
 * }
