/**
* Logger module which allows configuring the verbosity level.
*
* There are three levels of verbosity:
* 1. `info` - all messages will be logged,
* 2. `warning` - warning and errors will be logged,
* 3. `error` - only errors will be logged.
*
* Usage:
*
*      import { logger } from '@ckeditor/ckeditor5-dev-utils';
*
*      const infoLog = logger( 'info' );
*      infoLog.info( 'Message.' ); // This message will be always displayed.
*      infoLog.warning( 'Message.' ); // This message will be always displayed.
*      infoLog.error( 'Message.' ); // This message will be always displayed.
*
*      const warningLog = logger( 'warning' );
*      warningLog.info( 'Message.' ); // This message won't be displayed.
*      warningLog.warning( 'Message.' ); // This message will be always displayed.
*      warningLog.error( 'Message.' ); // This message will be always displayed.
*
*      const errorLog = logger( 'error' );
*      errorLog.info( 'Message.' ); // This message won't be displayed.
*      errorLog.warning( 'Message.' ); // This message won't be displayed.
*      errorLog.error( 'Message.' ); // This message will be always displayed.
*
* Additionally, the `logger#error()` method prints the error instance if provided as the second argument.
