title: What do helper and helper_method do?
body: <p><code>helper_method</code> is straightforward: it makes some or all of the controller's methods available to the view.</p>
  
  <p>What is <code>helper</code>? Is it the other way around, i.e., it imports helper methods into a file or a module?  (Maybe the name <code>helper</code> and <code>helper_method</code> are alike. They may rather instead be <code>share_methods_with_view</code> and <code>import_methods_from_view</code>)</p>
