Create "matryoshka" FMUs

The branch works as requested! There is only an issue at termination of the simulation, it seems that this is not properly passed to the inner fmus.
As an additional feature it would be nice to be able to rename the exposed variables.
And maybe executing the inner FMUs on different cores for performance gains?

@fajansen, can you give 1f8a2f3 a try?

[fajansen]

Termination of simulation works now as expected!
Renaming the exposed variables also works.

It might be confusing to always have support for all platforms in the container. For example the remoting mechanism would not properly detect that it should be enabled.

Would it be possible to provide a short documentation and example for this feature? Or have I overseen it? Thanks!

See https://github.com/CATIA-Systems/FMPy/blob/master/tests/test_fmu_container.py for a demo of the new (experimental) API.

Thanks. So the connections are defined manually in by the "Configuration". Would it be possible to read in an SSP file instead and create the Congfiguration from it?

Theoretically, yes.
