Apply custom classes to checkbox and its accompanying text input.

[mgurley]

Using 0.20.0 Rails 3 Branch.

I want custom CSS classes to apply to a checkbox input, plus its accompanying input. For example, a check box and its text box. In the following example for the Toyota answer:

a 'Ford'
a 'GM'
a 'Toyota' :string, :custom_class => "foo"

I want the custom css class to apply to both the checkbox and the text box like so:

<input type="checkbox" value="100" class="foo"> 
Toyota
<input type="text" class="foo">
