Add support for nested presenters

[alexwhitman]

Allows for nested PresentableInterface instances.

I've updated this with a better implementation. I'll look at adding tests tomorrow.

Now we have the problem of the copy pasted method, which I knew was going to happen. My current thinking is make your new one here static and call it in the view area and delete the one there.

[alexwhitman]

Updated to remove code duplication and added tests. I also updated the tests to use assertInstanceOf as it provides a more useful error message rather than just "Failed asserting that false is true.".

The modification of alexwhiteman is working great. Can you please accept his pull request ?

[robclancy]

This will be pull requested when I have time to think about the static method we have in there now (trying to think of a better solution, possibly a helpers.php file with it as a function). And when I have time to run the tests myself and then do all the updating for a release with the readme and tag stuff.

So it will be pulled in, just not until I am free from work a bit, being smashed right now.

Ok, sounds good to me !

And thanks for this package that really helps to keep the models light and clean !

Does this mean that if User has a Profile, and Profile has a presenter attribute of say transformed, then $user->profile->transformed will work (whereas at the moment, only $profile->transformed does)? If so, that would be great, as at the moment I'm still have to suck it up with accessors as most of my models are heavy related.

[alexwhitman]

@harhoo Yep, that's exactly what it does.
