Add spec

[kofalt]

Rather than viewing the diff, it might be easier to browse the branch's folder.

Left to do (will file tickets):

• Rename repository
• Add a basic root readme
• Others?

@kofalt Thanks for putting this together. I made a change to the gear sample readme to remove the redundant spec information now that the spec lives in this repo.

Considerations before merging:

• use "folder" or "directory" throughout the spec read me.
• Provide a way to contact us regarding network needs for gears. Use github issues or email, or something else?
• rename sample-gear folder to gear-sample. We will figure out a better alternative when renaming/moving this repo.

Suggestions addressed!

Merging based on discussion with Ryan!
