# 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.
