Whether an alternative benchmark format is being used such that instead
of starting for a certain instance specification with a workload
containing one task and running the broker for every number of tasks once
until the MAX_NUMBER_OF_TASKS is reached by increasing with
NUMBER_OF_TASKS_PER_RUN every time, we now run the benchmark
MAX_NUMBER_OF_TASKS times for every instance type specification every
time using exactly NUMBER_OF_TASKS_PER_RUN tasks.
Class represents the run of a benchmark which consists of different runs of
the broker application in which the four phases of the brokering process are
timed and the resulting costs overview is saved to file.
