+ * Welcome to Cocoa Lumberjack!
+ * 
+ * The project page has a wealth of documentation if you have any questions.
+ * https://github.com/robbiehanson/CocoaLumberjack
+ * 
+ * If you're new to the project you may wish to read the "Getting Started" page.
+ * https://github.com/robbiehanson/CocoaLumberjack/wiki/GettingStarted
+ * 
+ * 
+ * This class provides a log formatter that filters log statements from a logging context not on the whitelist.
+ * 
+ * A log formatter can be added to any logger to format and/or filter its output.
+ * You can learn more about log formatters here:
+ * https://github.com/robbiehanson/CocoaLumberjack/wiki/CustomFormatters
+ * 
+ * You can learn more about logging context's here:
+ * https://github.com/robbiehanson/CocoaLumberjack/wiki/CustomContext
+ *
+ * But here's a quick overview / refresher:
+ * 
+ * Every log statement has a logging context.
+ * These come from the underlying logging macros defined in DDLog.h.
+ * The default logging context is zero.
+ * You can define multiple logging context's for use in your application.
+ * For example, logically separate parts of your app each have a different logging context.
+ * Also 3rd party frameworks that make use of Lumberjack generally use their own dedicated logging context.

+ * If you're new to the project you may wish to read the "Getting Started" page.
+ * https://github.com/robbiehanson/CocoaLumberjack/wiki/GettingStarted
+ * 
+ * 
+ * This class provides a log formatter that prints the dispatch_queue label instead of the mach_thread_id.
+ * 
+ * A log formatter can be added to any logger to format and/or filter its output.
+ * You can learn more about log formatters here:
+ * https://github.com/robbiehanson/CocoaLumberjack/wiki/CustomFormatters
+ * 
+ * A typical NSLog (or DDTTYLogger) prints detailed info as [<process_id>:<thread_id>].
+ * For example:
+ * 
+ * 2011-10-17 20:21:45.435 AppName[19928:5207] Your log message here
+ * 
+ * Where:
+ * - 19928 = process id
+ * -  5207 = thread id (mach_thread_id printed in hex)
+ * 
+ * When using grand central dispatch (GCD), this information is less useful.
+ * This is because a single serial dispatch queue may be run on any thread from an internally managed thread pool.
+ * For example:
+ * 
+ * 2011-10-17 20:32:31.111 AppName[19954:4d07] Message from my_serial_dispatch_queue
+ * 2011-10-17 20:32:31.112 AppName[19954:5207] Message from my_serial_dispatch_queue
+ * 2011-10-17 20:32:31.113 AppName[19954:2c55] Message from my_serial_dispatch_queue
+ * 
+ * This formatter allows you to replace the standard [box:info] with the dispatch_queue name.
+ * For example:
+ * 
+ * 2011-10-17 20:32:31.111 AppName[img-scaling] Message from my_serial_dispatch_queue
+ * 2011-10-17 20:32:31.112 AppName[img-scaling] Message from my_serial_dispatch_queue
+ * 2011-10-17 20:32:31.113 AppName[img-scaling] Message from my_serial_dispatch_queue
+ * 
+ * If the dispatch_queue doesn't have a set name, then it falls back to the thread name.
+ * If the current thread doesn't have a set name, then it falls back to the mach_thread_id in hex (like normal).
+ * 
+ * Note: If manually creating your own background threads (via NSThread/alloc/init or NSThread/detachNeThread),
+ * you can use [[NSThread currentThread] setName:(NSString *)].
