* Setting up the MATSim {@link Config} so that it runs 20 iterations for a commercial vehicle
* population.
*
* @param folder the specific folder to which the output will be written. Also, it assumes the
* following files are available as input in the folder:
* <ul>
* <li>{@code population.xml.gz} of commercial vehicles, each person with a plan. Only
* activity locations are required. The {@link Leg}s are allowed to take {@code
* commercial} as mode.
* <li>{@code populationAttributes.xml.gz} indicating which individuals are part of the
* <i>commercial vehicle</i> subpopulation. For that the only attribute required, namely
* {@code subpopulation}, needs to be set as {@code commercial}.
* </ul>
*
* @param machine the computer on which the run is executed. This just sets up the number of
* threads without having to hard code it in the class. The following values are currently
* supported:
* <ul>
* <li>{@code HOBBES} using 40 threads;
* <li>{@code MAC_MINI} the machine in Engineering 2, Room 3-13.1, a dual core i7 using 4
* threads;
* <li>{@code MACBOOK_PRO} is Johan W. Joubert's laptop, a dual core i5 using 4 threads.
