The function take all districts mv_districts and divide them into clusters

Parameters
----------
mv_districts: :obj:`list` of int
List with all districts to be run.
n_of_districts: :obj:`int`
Number of districts in a cluster
output_info:
Info about how the run went
run_id: :obj:`str`
Identifier for a run of Ding0. For example it is used to create a
subdirectory of os.path.join(`base_path`, 'results')
base_path : :obj:`str`
Base path for ding0 data (input, results and logs).
Default is `None` which sets it to :code:`~/.ding0` (may deviate on
windows systems).
Specify your own but keep in mind that it a required a particular
structure of subdirectories.

Parameters
----------
mv_grid_districs : :obj:`list`
Integers describing grid districts
run_id: :obj:`str`
Identifier for a run of Ding0. For example it is used to create a
subdirectory of os.path.join(`base_path`, 'results')
failsafe : bool
Setting to True enables failsafe mode where corrupt grid districts
(mostly due to data issues) are reported and skipped. Report is to be
found in the log dir under :code:`~/.ding0` . Default is False.
base_path : :obj:`str`
Base path for ding0 data (input, results and logs).
Default is `None` which sets it to :code:`~/.ding0` (may deviate on
windows systems).
Specify your own but keep in mind that it a required a particular
structure of subdirectories.
Returns
-------
msg : :obj:`str`
Traceback of error computing corrupt MV grid district
.. TODO: this is only true if try-except environment is moved into this
fundion and traceback return is implemented
Note
-----
Consider that a large amount of MV grid districts may take hours or up to
days to compute. A computational run for a single grid district may consume
around 30 secs.
