/**
The default logger logs only `error` and `warn` to console. To provide custom logging from Permissions:

  - implement `IPermissionsLogger` methods (or just create a plain JS object with these)

  - pass an instance to [`setLogger()`](/miscellaneous/variables.html#setLogger)

 ```js
  import { setLogger, IPermissionsLogger } from '@superawesome/permissions'

  class MyLogger implements IPermissionsLogger {
    error(message: string, data?: any) {
      console.error(message, data);
    },
    ...
  }

  setLogger(new MyLogger());

  // internally its used like this

  getLogger().warn('Something smelly!', {data: 'to prove it'})

  // but you only really need it if you develop a plugin etc

 ```

 To disable logging completely:

 ```js
  setLogger(null);

 ```
