Documentation - Model Annotation / Traits

[notryanb]

Problem Description

Re: Better Documentation #853 Models

Documentation on model annotations (Queryable, Identifiable, Insertable, etc...) and the code they generate is sparse and spread out over the API documentation. Available guides (Getting Started & All About Updates) make mention of the derivable traits, but do not go into much depth.

What are you trying to accomplish?

• Create a central location to reference all the traits that can derived
• Explain why these derives are useful or important
• Explain how to implement the traits without the struct annotations (for comparison or writing custom ones)
• Provide specific example use cases (and even erroneous cases?).

Checklist

• I have already looked over the issue tracker for similar issues.

Now that df5a6e8 has been merged, I believe this can now be closed.
