Add section on settings analysis

I will add some links here to relevant posts on Discord where strategies for tuning of settings have been discussed, as these can make a good starting point for a section in the docs dealing with this.

@bjornoleh Added this section for Evaluate Basal in dev: https://iaps.readthedocs.io/en/dev/Analyze/EvaluateBasal.html. Feel free to take a look and edit/add as needed before we promote to main. I will create a page for CR as well.

@bjornoleh created CR page as well: https://iaps.readthedocs.io/en/dev/Analyze/EvaluateCR.html

I will leave this open until you have the chance to review/edit in dev.
