Configurations

A run configuration is a specification of what parts to use in the simulation and how to configure each part. Parts include the list and order of models to run, where to get the input values, where to store the output data, what years to simulate, what tables to store into the UrbanSim baseyear and simulation caches , etc. Each of these parts in turn may be configurable. The configuration for a travel model, for instance, may specify which values to use from the land use models, and what travel model results to extract in order to use them in the land use models.

Configurations are used in many places in Opus. Typically, they are specified via a Python dictionary that then is used to create an instance of the Configuration class.
