Create a collection of radio inputs for the attribute. Basically this
 helper will create a radio input associated with a label for each
 text/value option in the collection, using value_method and text_method
 to convert these text/value. You can give a symbol or a proc to both
 value_method and text_method, that will be evaluated for each item in
 the collection.

 == Examples

   form_for @user do |f|
     f.collection_radio_buttons :options, [[true, 'Yes'] ,[false, 'No']], :first, :last
   end

   <input id="user_options_true" name="user[options]" type="radio" value="true" />
   <label class="collection_radio_buttons" for="user_options_true">Yes</label>
   <input id="user_options_false" name="user[options]" type="radio" value="false" />
   <label class="collection_radio_buttons" for="user_options_false">No</label>

 It is also possible to give a block that should generate the radio +
 label. To wrap the radio with the label, for instance:

   form_for @user do |f|
     f.collection_radio_buttons(
       :options, [[true, 'Yes'] ,[false, 'No']], :first, :last
     ) do |b|
       b.label { b.radio_button + b.text }
     end
   end

 == Options

 Collection radio accepts some extra options:

   * checked  => the value that should be checked initially.

   * disabled => the value or values that should be disabled. Accepts a single
                 item or an array of items.

   * collection_wrapper_tag   => the tag to wrap the entire collection.

   * collection_wrapper_class => the CSS class to use for collection_wrapper_tag

   * item_wrapper_tag         => the tag to wrap each item in the collection.

   * item_wrapper_class       => the CSS class to use for item_wrapper_tag

   * a block                  => to generate the label + radio or any other component.
