Improve ipywidgets layout for ppa

@aloctavodia I thought about this one...

We have many parameters in the pz.ppa that we should allow users to interact with. I have just tried the widgets (not the functionality) to include most of them.

Do let me know what you think about this, also feel free to suggest changes.

[aloctavodia]

Not sure about this. Both the target and the boundaries should be defined before-hand, I don't see clearly why one would like to interact with them. Also if those values are changed the hole elicitation should start again, because previous values will become obsolete, so that's equivalent to just run ppa again.

For the "references" I see why a user may want to change it during elicitation.

Ah I see...
What abt we remove the lower_bound, upper_bound and target along with no lower bound and no upper bound checkboxes.

And keep only draws and references for the user interaction

[aloctavodia]

At this point draws is only used once, so it does not make sense to change it interactively. After #317 It will be used everytime we "resample", but even then, I'm not sure that this is something the user may want to interact with. Actually, in the future we may want to remove that option and use a fixed number that works well overall.

So, we should only add the "references" box

[rohanbabbar04]

Noted...
We then keep the look of the interactive mode similar to the image

In the Horizontal box, we have our references(input parameters) followed by the radio buttons and then the carry-on/return prior button.
Is that fine?

[aloctavodia]

yes
