Models and Schemas, Batch 3: Task Management

[slaarti]

Description

This is the third batch of models and schemas for #72, making up something like a simple task management system.

Changes

Models, schemas, and doc/docstring updates for:

• Tier
• Department
• User
• Story (Replacement for Project in this model set to reduce confusion with the Project that's part of the models defined in tests.)
• Task

One thing I want to note is that, in docs/advanced/joins.md, the examples between the "Getting Joined Data Nested" section and the later "One-to-One Relationships" appear to be identical? It feels unnecessarily redundant to me, but I'm not sure what to do about it. I just wanted to get it noted for the review and see if anyone else who reads this has any ideas.

Checklist

• I have read the CONTRIBUTING document.
• My code follows the code style of this project.
• I have added necessary documentation (if appropriate).

True, I belive one of those was in another page, probably Advanced CRUD usage, and eventually I changed and didn't notice the repetition.

How would you like to proceed, @slaarti?

Sorry, right, I meant to say that you might as well go ahead and merge, since this PR didn't really touch that and I forget if one of the later ones to come do either. If none of them do, then I suppose that's something to maybe work on after #72 is closed out.
