title: Error when developing template context processor
body: <p>I'm in the midst of developing my first template context processor. </p>
  
  <p>It's generating an error: <code>Module "bookings.context_processors" does not define a "context_processors" attribute/class</code></p>
  
  <p>I've followed a number of examples however this isn't making too much sense to me. Can someone tell me why this error is being generated?</p>
  
  <p>Code's pretty simple:</p>
  
  <p><strong>context_processors.py</strong>:</p>
  
  <pre><code>from bookings.models import Booking, BookingItem
  
  def injectBookingObject(request):
      try:
          booking = request.session['bookingID']
          bookingOptions = BookingItem.objects.all().filter(bookingID = booking)
          return {
              'bookingContents' : bookingOptions,
          }
      except:
          return {}
  </code></pre>
  
  <p><strong>settings:</strong></p>
  
  <pre><code>TEMPLATE_CONTEXT_PROCESSORS = (
      *** usual ones *****
      'bookings.context_processors'
  )
  </code></pre>
  
  <p><strong>views.py</strong>:</p>
  
  <pre><code>def activity_detail(request, slug):
