Result decorator

[martinciu]

Hi,

As I described in #364 I needed a way to merge attributes returned by ElasticSearch with model loaded from database. I needed to get merge them with values returned from scritp_fields (see #363).

So now search results returns array of Results::Item whenever you get load models for results or not and passes missing methods first to attributes array and than to loaded model.

@martinciu Hi, I like the refactoring you did, sorry it took me so long to get to it.

I'm not sure about returning Item instances when using the :load option, though. I think we should have something like Sunspot's each_with_hit (see #406 and #261).

I'll try to have a look into this shortly.

Hi @karmi I'll take a look at Sunspot's each_with_hit

thanks!

@martinciu What do you think about the each_with_hit approach? I think it would be better then to decorate the results directly? Also notice the refactoring I did in https://github.com/karmi/tire/tree/refactoring/results to better support people needing to change the code which loads data from the database...

Closing in favour of each_with_hit (or similar) feature.
