Hi,

We have developed, for our project's needs, a object wrapper mechanism to help getting content data from different ContentTypes without writing too many specific codes into the twig templates or the main controller.

The code is here : https://github.com/Erilan/ezobject

And the description of what it does exaclty is here :
https://github.com/Erilan/ezobject/wiki/eZ-Object-Wrapper

We would like to make a Pull Request in order to integrate this contribution within the eZ Publish kernel, but I don't really know where in the kernel it would be done... so every remarks are welcome

NB : Actually, this bundles works within eZ Publish 5.3 projects.
We did not test it in eZ Publish 5.4, but it should work also.
