Why are tests for power spectrum included here?

[Lucia-Fonseca]

It looks very good! Great job, Ian.
Two small changes:

• Add plt.show() to avoid outputing unnecesary text
• Name of the config file for merger rates
• I still see test_camb.py and test_class.py.

I think you can add a semicolon at the end of a statement
plt.xlabel('This is an x label');
to avoid extra text output in the notebooks without the need of a plt.show

That works too, thanks @jucordero!

Is the intention that the user would run these notebooks themselves? I think they make more sense as part of the documentation (perhaps using nbsphinx?) but if that is the case they should probably be in the docs directory not the examples directory. Particularly because everything in examples is mirrored to the skypyproject/examples repository and we shouldn't distribute them in this way if we don't expect the user to run them.

The idea is to have something similar to CAMB DEMO

[Lucia-Fonseca]

Looks good.

These look good, let's merge them as they are and work out how we want to incorporate them with the documentation in the future.
