Port DumbledORM ResultSet

[sandermarechal]

I came across a comment from you that you were interested in porting the ResultSet class from DubmledORM to Paris. I really liked DombledORM's approach so I started using it in my project as well. This change adds the ResultSet to Paris, allowing for some fancy jQuery-like syntax. Example:

Model::factory('Widgets')->filter('expired')->find_many()->delete();

I ported it to Paris, which seemed like the most logical choice to me at the time. If you prefer, I could also try to implement it on Idiorm itself, which would fix your j4mie/idiorm#22

I like this solution

Awesome. Just now seeing this. :)

Thank you for the pull request. It cannot be merged into Paris though as it belongs on a layer below in Idiorm itself.

In the latest commit on the develop branch of Idiorm (j4mie/idiorm@5a6d20c) ResultSet functionality has been added.

To enable find_many() to return result sets by default set the following configuration option:

ORM::configure('return_result_sets', true);

Then you can run any Paris methods against the results as @sandermarechal has mentioned above.
