Analysis - sample tab auto analysis / MOI node tidy up

Add sample / Patient link on MOI node

Explain / document "strict zygosity"

-------------

Also, the automatically created analysis "sample tab auto analysis" is showing up in sample related analyses

* Go to a sample
* Click variants tab, select dropdown
* Reload sample page - sample tab auto analysis is at bottom of sample page

Reproduce the reported behavior by opening a sample, using the Variants tab dropdown, and reloading the sample page. Inspect the code behind the MOI node and the sample-related analyses view; done means the MOI node links to the sample or Patient, “strict zygosity” is documented, and “sample tab auto analysis” no longer appears there.
