Simulation setup

To simulate FMU `MixtureGases.fmu` with OMSimulator run
```bash
$ wine64 /var/lib/jenkins/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulatorBinaries/OMSimulator-mingw64/bin/OMSimulator.exe --workingDir=/var/lib/jenkins/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulator/testsuite/fmi-cross-check/fmi-cross-check/results/2.0/me/win64/OMSimulator/v2.1.1/Dymola/2017/MixtureGases --stripRoot=true --skipCSVHeader=true --addParametersToCSV=true --suppressPath=true --timeout=60 /var/lib/jenkins/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulator/testsuite/fmi-cross-check/fmi-cross-check/results/2.0/me/win64/OMSimulator/v2.1.1/Dymola/2017/MixtureGases/MixtureGases.lua
```

Lua file:
```lua
-- lua file for MixtureGases.fmu
oms_setTempDirectory('/tmp/cross-check')
oms_newModel('model')
oms_addSystem('model.root', oms_system_sc)

-- instantiate FMU
oms_addSubModel('model.root.fmu', 'MixtureGases.fmu')

-- simulation settings
oms_setResultFile('model', 'MixtureGases_out.csv')
oms_setLoggingInterval('model', 0.002)
oms_setStartTime('model', 0.0)
oms_setStopTime('model', 1.0)
oms_setTolerance('model', 1e-06, 0.0001)
oms_setVariableStepSize('model', 1e-12, 1e-12, 0.002)

-- instantiate, initialize and simulate
oms_instantiate('model')
oms_initialize('model')
oms_simulate('model')
oms_terminate('model')
oms_delete('model')
```
