Simulation setup

To simulate FMU `MixtureGases.fmu` with OMSimulator run
```bash
$ wine64 /var/lib/jenkins2/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulatorBinaries/OMSimulator-mingw64/bin/OMSimulator.exe --stripRoot=true --skipCSVHeader=true --addParametersToCSV=true --suppressPath=true --timeout=60 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_setStartTime("model", 0.0)
oms_setStopTime("model", 1.0)
oms_setTolerance("model", 1e-08, 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")
```
