  # Class Methods
  
  # This method is most likely called from the ContentHelper.render_collection
  # method which aggregates pages into a collection, based on parameters it 
  # recieves. This method then calls Page.aggregate with these parameters.
  # The Page.aggregate method comes with a defaults hash. These options are
  # partially or entirely overwritten by the options hash. Afterwards the merged
  # parameters are used to query the DB for Pages matching these parameters.
