Add documentation

[tjbenton]

The documentation will be done using the docs library.

The following files need to be document

• [x] cli.js
• [x] documents.js
• [x] index.js
• [x] input.js
• [x] models.js
• [x] output.js
• [x] output/
  • [x] console.js
  • [x] couchbase.js
  • [x] default-options.js
  • [x] folder.js
  • [x] index.js
  • [x] sync-gateway.js
  • [x] zip.js
• [x] utils.js

We also should create a wiki on here or better yet build a site that people can see the output as they edit it a file.
