 h2. Listing records with paging
 
 Use the @arvados.util.keyset_list_all@ helper method to iterate over all the records matching an optional filter.  This method handles paging internally and returns results incrementally using a Python iterator.  The first parameter of the method takes a @list@ method of an Arvados resource (@collections@, @container_requests@, etc).
