Let's assume, that I have two entity classes:  

`\AppBundle\Entity\User` - user provider;  

`\AppBundle\Entity\Article` - simple article.

The `Article` class also have these properties:  

`author` - indicating on user which created this particular entity;  

`updatedBy` - indicating on user which lately updated content of particular article.

How to pass currently logged user object to `Article` entity to set specific values on `author` and/or `updatedBy` properties on backend generated by [EasyAdminBundle](https://github.com/javiereguiluz/EasyAdminBundle) on *Symfony 3.0.1*?
