Feature/45 reset

Closes #45

[markaren]

We should probably consider changing the function definitions for

    def _get_fmu_state(self) -> Dict[int, Any]:
    def _set_fmu_state(self, state: Dict[int, Any]):

To use str as key, this way users may override _get_fmu_state adding custom properties to it.

Dammit, I went about this in the wrong way. We could just re-instantiate the Python code as a whole. That would guarantee correct behavior..

Good to go. Works with integration test and FMI4j.

As the Python class definition won't change, I would recommend storing the pClass object instead of pModule as PySlaveInstance member. So initialize will only dismiss the previous instance and create a new one.

That seems to crash both pyfmi and FMI4j

Ok so let's stick with your code then. Thanks for trying.
