!> @brief This module defines the derived type ObsOutputListType
!!
!! This module contains a list of ObsOutputType objects and
!! methods needed for coordinating between an ObsType object and its
!! ObsOutputType objects.  Like ObsOutputType, ObsOutputListType is
!! needed only for processing continuous observations.
