`include_IAK` is of type `str`, however, it is being checked as a boolean

[kasra-keshavarz]

Problem Statement

The include_IAK variable is of type str after being read from the control file. While creating NetCDF file of the network topology, however, it is being checked as a boolean value:

...          
    create_and_fill_nc_var(ncid, 'manning', 'f8', 'n', False, \
                           shp_river['manning'].values.astype(float), \
                           'manning', '-')
    if include_IAK:
        create_and_fill_nc_var(ncid, 'IAK', 'int', 'n', False, \
                            shp_river[river_order].values.astype(int), \
                            'River Order', '-')
...

Proposed solution(s)

Either the dtype of include_IAK must be corrected, or, the if statement should be changed to the following:

...
    if include_IAK == 'True':
        create_and_fill_nc_var(ncid, 'IAK', 'int', 'n', False, \
                            shp_river[river_order].values.astype(int), \
                            'River Order', '-')
...
