feat(collaborators): list objects, modules, and functions that an object uses

[gregswindle]

User story

As a developer/designer,
I need to see the full list of dependencies invoked within an object
In order to maintain a SOLID GRASP of my software.

Acceptance criteria

• 1. Every prototypical object invoked by an object appears as a "Collaborator."
• 2. Each Collaborator entry has an array of invocation ranges.

⚡ Rule developers must use the eslint:rule subgenerator!

When you create a new rule, be sure to use the eslint:rule subgenerator, since it will

1. Create a stubbed rule,
2. The rule's stubbed BDD specs,
3. As well as the rule's documentation.

See eslint-plugin development environment for details.
