def	main ()

Detailed Description

Construct hillslope-slope position units.

The main procedure:
- 1. Assign unique ID to each type of slope position unit with hillslopes, and
   assign the up-down relationships according to the slope position sequence.
- 2. Statistics the landuse types and areas within each slope position units.
- 3. Merge hillslope with incomplete slope position sequences to other hillslopes
   of the same subbasin.
- 4. Merge subbasin with incomplete slope position sequences to its downstream,
   for the outlet subbasin merge to its upstream.

    @changelog:
    - 17-08-14  lj - initial implementation.
    - 18-02-08  lj - compatible with Python3.
    - 18-11-05  lj - update according to :func:`ImportReaches2Mongo:read_reach_downstream_info`.
                     Add type hints based on typing.
