### Logger

Logger functions with configurable verbosity.

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:

```js
const logger = require( '@ckeditor/ckeditor5-dev-utils' ).logger;

// All messages will be displayed.
const infoLog = logger( 'info' );
infoLog.info( 'Message.' );
infoLog.warning( 'Message.' );
infoLog.error( 'Message.' );

// This First message won't be displayed..
const warningLog = logger( 'warning' );
warningLog.info( 'Message.' );
warningLog.warning( 'Message.' );
warningLog.error( 'Message.' );

// Only the last message will be displayed.
const errorLog = logger( 'error' );
errorLog.info( 'Message.' );
errorLog.warning( 'Message.' );
errorLog.error( 'Message.' );
```
