Support ActiveModel-type find functionality

[palexander]

Supporting a "find" functionality similar to ActiveModel would be great. This will help people familiar with ActiveRecord and other common Ruby ORMs to use Goo a little easier.

I imagine several types of calls:

Person.find(:all)
Person.find(["paul", "manuel"])
Person.find("paul")
Person.find("http://goo.org/metadata/person/paul")
Person.all # wraps Person.find(:all)
Person.where(:name => "paul", :phone => "555-555-5555")

More examples here: http://guides.rubyonrails.org/active_record_querying.html

When searching by IRI we need to pass an IRI object ...

Person.find(RDF::IRI.new("http://goo.org/metadata/person/paul"))

And for nested objects .... people that live in a country with name Spain ...

Person.where(:lives => { :name => "Spain" })

The same can be achieved in two steps ...

spain = Country.find("Spain")
Person.where(:lives => spain)

Both are supported.
