-    # The Active Record Helper makes it easier to create forms for records kept in instance variables. The most far-reaching is the +form+
-    # method that creates a complete form for all the basic content types of the record (not associations or aggregations, though). This
-    # is a great way of making the record quickly available for editing, but likely to prove lackluster for a complicated real-world form.
-    # In that case, it's better to use the +input+ method and the specialized +form+ methods in link:classes/ActionView/Helpers/FormHelper.html
-    module ActiveRecordHelper
-      # Returns a default input tag for the type of object returned by the method. For example, if <tt>@post</tt>
-      # has an attribute +title+ mapped to a +VARCHAR+ column that holds "Hello World":
-      #
-      #   input("post", "title")
-      #   # => <input id="post_title" name="post[title]" size="30" type="text" value="Hello World" />
-      def input(record_name, method, options = {})
-        InstanceTag.new(record_name, method, self).to_tag(options)
-      end
-
-      # Returns an entire form with all needed input tags for a specified Active Record object. For example, if <tt>@post</tt>
-      # has attributes named +title+ of type +VARCHAR+ and +body+ of type +TEXT+ then
-      #
-      #   form("post")
-      #
-      # would yield a form like the following (modulus formatting):
-      #
-      #   <form action='/posts/create' method='post'>
-      #     <p>
-      #       <label for="post_title">Title</label><br />
-      #       <input id="post_title" name="post[title]" size="30" type="text" value="Hello World" />
-      #     </p>
-      #     <p>
-      #       <label for="post_body">Body</label><br />
-      #       <textarea cols="40" id="post_body" name="post[body]" rows="20"></textarea>
-      #     </p>
-      #     <input name="commit" type="submit" value="Create" />
-      #   </form>
-      #
-      # It's possible to specialize the form builder by using a different action name and by supplying another
-      # block renderer. For example, if <tt>@entry</tt> has an attribute +message+ of type +VARCHAR+ then
-      #
-      #   form("entry",
-      #     :action => "sign",
-      #     :input_block => Proc.new { |record, column|
-      #       "#{column.human_name}: #{input(record, column.name)}<br />"
-      #   })
-      #
-      # would yield a form like the following (modulus formatting):
-      #
-      #   <form action="/entries/sign" method="post">
-      #     Message:
-      #     <input id="entry_message" name="entry[message]" size="30" type="text" /><br />
-      #     <input name="commit" type="submit" value="Sign" />
-      #   </form>
-      #
-      # It's also possible to add additional content to the form by giving it a block, such as:
-      #
-      #   form("entry", :action => "sign") do |form|
-      #     form << content_tag("b", "Department")
-      #     form << collection_select("department", "id", @departments, "id", "name")
-      #   end
-      #
-      # The following options are available:
-      #
-      # * <tt>:action</tt> - The action used when submitting the form (default: +create+ if a new record, otherwise +update+).
-      # * <tt>:input_block</tt> - Specialize the output using a different block, see above.
-      # * <tt>:method</tt> - The method used when submitting the form (default: +post+).
-      # * <tt>:multipart</tt> - Whether to change the enctype of the form to "multipart/form-data", used when uploading a file (default: +false+).
-      # * <tt>:submit_value</tt> - The text of the submit button (default: "Create" if a new record, otherwise "Update").

-      # provided.
-      #
-      # This <tt>DIV</tt> can be tailored by the following options:
-      #
-      # * <tt>:header_tag</tt> - Used for the header of the error div (default: "h2").
-      # * <tt>:id</tt> - The id of the error div (default: "errorExplanation").
-      # * <tt>:class</tt> - The class of the error div (default: "errorExplanation").
-      # * <tt>:object</tt> - The object (or array of objects) for which to display errors,
-      #   if you need to escape the instance variable convention.
-      # * <tt>:object_name</tt> - The object name to use in the header, or any text that you prefer.
-      #   If <tt>:object_name</tt> is not set, the name of the first object will be used.
-      # * <tt>:header_message</tt> - The message in the header of the error div.  Pass +nil+
-      #   or an empty string to avoid the header message altogether. (Default: "X errors
-      #   prohibited this object from being saved").
-      # * <tt>:message</tt> - The explanation message after the header message and before
-      #   the error list.  Pass +nil+ or an empty string to avoid the explanation message
-      #   altogether. (Default: "There were problems with the following fields:").
-      #
-      # To specify the display for one object, you simply provide its name as a parameter.
-      # For example, for the <tt>@user</tt> model:
-      #
-      #   error_messages_for 'user'
-      #
-      # To specify more than one object, you simply list them; optionally, you can add an extra <tt>:object_name</tt> parameter, which
-      # will be the name used in the header message:
-      #
-      #   error_messages_for 'user_common', 'user', :object_name => 'user'
-      #
-      # If the objects cannot be located as instance variables, you can add an extra <tt>:object</tt> parameter which gives the actual
-      # object (or array of objects to use):
-      #
-      #   error_messages_for 'user', :object => @question.user
-      #
-      # NOTE: This is a pre-packaged presentation of the errors with embedded strings and a certain HTML structure. If what
-      # you need is significantly different from the default presentation, it makes plenty of sense to access the <tt>object.errors</tt>
-      # instance yourself and set it up. View the source of this method to see how easy it is.
