Add remaining models from spec into engine

[digitalWestie]

Hello, I've been working on this to use with an app I'm building. I'm not very well versed with the spec or mongoid so any help / feedback would be appreciated.

Had a quick look - It's looking good! I see there are some TODO in the code. Is this ready for review, or should I wait for those TODO's to be done?

[digitalWestie]

Oh, forgot about some of those. It would be good if you could review it. That way I can see if I'm on the right track regarding the spec.

Can you confirm that the autoload_paths change is necessary?

I'll squash the commits into one. I'm reverting the date format stuff because the date format should respect ISO 8601, which the new regex does not. You should just reformat your data to match the regex. Popolo allows for truncated dates like 2004, 2004-01.

Nothing uses DateTimeString yet, so I won't merge that. I'll push my commits soon.

I've pushed my commits. Thanks for moving this forward! Please switch to HEAD for additional commits.

Good stuff @jpmckinney - on the topic of date validation I see I've got it wrong on respecting ISO 8601. However, the reason I went messing with the dates was due to errors cropping up during validation. It tries to parse the date and then fails during validation, that's why I came up with a custom validation method.

Stick this test in organization_spec.rb and you'll see what I mean:

it "can validate without causing errors" do
    subject = FactoryGirl.create(:organization)
    subject.founding_date = ''
    subject.valid?.should == false
end

Which results in:

ArgumentError: invalid date
    from (irb):11:in `parse'
    from (irb):11

I believe the cause is in date_string.rb

def demongoize(object)
  object.nil? ? nil : Date.parse(object)
end

Date.parse() doesn't handle '2004' or 2004-11:

2.1.2 :014 > Date.parse('2004-11')
ArgumentError: invalid date
    from (irb):14:in `parse'
    from (irb):14

Thoughts?

I've pushed commits (and specs) to handle these cases. Thanks!
