NO_OF_SIMULATIONS INPUT_FILE_1 ALGORITHM_1 SIM_TYPE_1 ... INPUT_FILE_N ALGORITHM_N SIM_TYPE_N NO_OF_REPETITIONS

- the simulations are performed, and trace files are generated, but there is no output of statistical data - TraceFileStatisticAnalyzer objects are stored in a HashMap; the idea is to output just one statistical analysis file per simulation (this is the next step)
