[User Story] As a developer, I want a singular repository class so that I can easily use multiple repositories

**Given...**
Multiple repositories are referenced within a method or class

**When...**
The need for accessing multiple repositories arises

**Then...**
Construct via factory, or pass in via DI a UnitOfWork class that contains all `IRepositories` to allow easy use of repositories.

- This will become increasingly necessary when more repositories are created.
- This is essentially containerizing repositories within a single class.

Acceptance Criteria:
- Will have a UnitOfWork version containing multiple DALs.
- Will have a FakeUnitOfWork version containing multiple FakeRepositories.
