Add backward stack trace printing.

[windelbouwman]

Idea: create more detailed stack traces using the backwards library: https://github.com/bombela/backward-cpp

Note: I just added the stack trace printer to one node, I can add it to the others if this seems a good idea.

Sorry for this late answer. In my opinion this is a good hint for debugging. Other than that, it does not improve the project but adds an additional dependency.
