Viranch pointed out where sender and receiver go, I was able to start to
figure things out and am extremely close to finally finishing this project.

I would recommend this way of connecting signals in, since errors will be<br>
immediately caught (AttributeError in case of wrong / missing signal) rather<br>
than silently ignored.<br>
<br>
The only case in which option 2 should be used is if the C++ signal has not<br>
been bound to the Python bindings.<br>
