The Run Method

Input:

model_configuration

- a Configuration object that determines project types and settings for each type (see Model Configuration of Section 23.4.2).

location_set

- a Dataset object to be updated.

development_event_set

- a DevelopmentEventDataset with development events to be used to update the locations.

development_type_set

- an object of class DevelopmentTypeDataset.

current_year

- an integer value determining the year of events by which the locations are updated.

Algorithm:
The method adds/replaces/removes development contained in development_event_set to/by/from location_set. It updates the location attributes given by 'units' of model_configuration. The type of change can be given in event set attribute 'type_of_change' as 'A' for add, 'R' for replace and 'D' for delete. The default type of change is 'A'. The method also determines a new development type for each location depending on the existing development.

Output: 
Returns a tuple of indices of locations that were modified, and indices of development events that were processed.
