logging-rails | Railtie for integrating the Logging framework with Rails

Add the ```logging-rails``` railtie gem to your Rails project’s Gemfile and run ```bundle install```. The Logging framework sets the global log level from the ```log_level``` configuration item. However, each class can be assigned its own log level. This is very useful when debugging a single controller or model in your Rails application. Consider the example below. The overall log level for the application is set to ```:info```, but the log level for the User model and controller is set to ```:debug```. When using the logging railtie, a small display of the current logging configuration will be displayed when Rails is in development mode (environment). A description of the display can be found [here](https://github.com/TwP/logging/blob/master/lib/logging.rb#L400). This is useful for understanding more complex logging configurations. It can be annoying in day-to-day usage. To disable, set the ```show_log_configuration``` setting to false in the environment specific configuration file.
