Add "knowns associates" table, repo, interactor, tests, and controller.

[reyesml]

Users should be able to CRUD against an "Associates" table.

Users can have multiple associates.

Associates will have:

• FirstName
• LastName
• *baseModel

Pretty basic. New fields will be added as features demand.

• [x] table
• [x] repo
• [x] interactor
• [x] tests
• [x] controller
• [x] controller tests

Shelving this feature until after the "self" tools are complete.
