title: Is there a ruby/rails gem that makes scoping dates easy
body: <p>anyone know of a gem that makes scoping dates easy? I'd love to do Model.this_year(:created_at).where()... etc. Thought I heard of one once.</p>
  
  <p>I was thinking something along the lines of dues_paid_this_year or updated_at_two_hours_ago. A gem that could do this like search_logic by creating dynamic scopes would make my world lovely</p>
