Add a model-building checklist

[phillipsclynn]

Preliminary checklist for selecting factors:

1) Correct baseline prevalence and distribution
2) Modifiable factors only
3) Factors that must be relevant to the Cdn context; either they are used in Canada, has the possibility of use/application and this could impact AMR (e.g., FQ in broiler chicken)
4) Factors: updating both the OR and the frequency of occurrence (distribution around the frequency of occurrence).
5) Factors at the correct node
6) Addressing factors where site of AMR measurement differs from the site of factor application (e.g., organic production measured at retail)
7) Non-selective versus selective media
8) Findings based on phenotypic data versus genomic data; quantitative AMR
9) Correct bacterial recovery at retail
10) Correct consumption from food book.

Items in italics are handled by the Hub module, using:

• CIPARS placement data for EC/SAL in chicksns
• Some Campy from Angie
• All by sub-type (e.g. by Campy species, by Salmonella serovar.

Hi team! I have a draft of this section in a Google Doc here:
https://docs.google.com/document/d/1sq5VxA7E6YCuznU8JQEknqCRK0xiabVXETwZh1DPnRg/edit?usp=sharing

It will eventually be added to the documentation site between our sawmill and Analytica sections. Would really appreciate any suggestions and comments from the team. Thanks!
