Adds a virtual attribute to models, that plays nice with forms etc

example:

    class MyModel < ActiveRecord::Base

      virtual_attribute :foo, :boolean => true, :attr_type => :attr_accessible

      virtual_attribute :bar, :boolean => true, :attr_type => :attr_accessible

    end

    params = {:foo => '1', :bar => 'false'}

    thing = MyModel.new(params)

  

    thing.foo #=>true

    thing.bar #=> false

Virtual attributes can be set to :boolean => true

  - This will parse ['yes', 'true', '1', 1] to be true

  - and ['no', 'false', '0', 0] to be false

  - otherwise will be nil

  - this allows them to be used transparently with checkboxes etc in forms

If using attr_accessible in your model, the virtual attribute should be added to the list to, or you can pass:

    :attr_type => :attr_accessible 

    

as an option as shown above to have it done for you

Will document better later, until then:
