Update docblock for data transformer interface. Support method signature was wrong, object name is wrong too. It can be object or array depending if we normalize / denormalize.

Can you switch to 2.4 as target branch as it's a bug fix please?

I think this points to a deeper problem. The DataTransformerInterface does not differentiate the direction of transformation.

Indeed, but we must merge this PR anyway. @cacahouwete let me know when the rebase is done.

It has been done like this by design.

@soyuka I think it's bad design. Look at the code the users have to write. It's not clean.

In fact we wanted to implement the automapper and even make this part optional. We didn't wanted to add 2 interfaces for this.

@dunglas Rebase done.
