run_config and estimate_config are collections of
parameters that control the run() and estimate() method,
respectively. In addition to the mentioned entries ``compute_capacity_flag'',
``capacity_string'', ``weights_for_simulation_string'', and ``weights_for_estimation_string'', they can contain entries
``sample_proportion_locations'' and ``sample_size_locations''. Both entries
control the size of sampled alternatives, the first one as a relative number,
the latter one as an absolute number. The latter one has a priority over the
first one.
estimate_config can also contain an entry 'chunk_specification_for_estimation',
which should be an object of class ChunkSpecification (see Section 22.7.3).
It controls the number of chunks in which the sampling is done for the estimation.
