/**
 * 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.
