Add View tutorial

[jnsbck]

I added a tutorial to introduce the concepts behind Views and Modules, since I think understanding the basics is really helpful to work with Jaxley effectively and at the moment you'd have to figure it out yourself from the API docs.

This is a first draft. Your feedback would be much appreciated.

I will have a look later. Is it ok if I just push to the branch?

[jnsbck]

Yes, fine with me.

Awesome!

I think it's great to have a central place where all of these concepts are explained, and I think that users will find this very useful.

However, I would not suggest to make it the first tutorial---it is quite detailed and it is not very satisfying to end the first tutorial with "hey here is your network, but you cannot do anything with it yet".

So, I suggest the following (which I will push in a second, but we can ofc revert if you disagree):

• I copied some parts of your tutorial to 01_morph_neurons.ipynb, in particular using cell.nodes and cell.branch(0).nodes to inspect the module.
• I added links to your new tutorial in the 01_ tutorial and once in the 03_ tutorial
• I added your new tutorial as the first tutorial of the Advanced tutorials section (I created this new section in New tutorials on indexing and parameter sharing #464)

Let me know what you think!

On a side-note, I just realized that all our links in tutorials are still going to the old website...I changed this now.

* I copied some parts of your tutorial to `01_morph_neurons.ipynb`, in particular using `cell.nodes` and `cell.branch(0).nodes` to inspect the module.

* I added links to your new tutorial in the `01_` tutorial and once in the `03_` tutorial

* I added your new tutorial as the first tutorial of the `Advanced tutorials` section (I created this new section in [New tutorials on indexing and parameter sharing #464](https://github.com/jaxleyverse/jaxley/pull/464))

Sounds great to me! I added it as 00_ mainly cos I was not sure where to put it. I also very much like having an "advanced" section.

Feel free to merge it.
