Given a set of document/revision IDs, returns the document bodies (and, optionally, attachment data) for each ID/revision pair specified.

### Options

* `options.docs`: An array of `id` and `rev` pairs representing the revisions to fetch.
  - `id`: ID of the document to fetch.
  - `rev`: Revision of the document to fetch. If this is not specified, all available revisions are fetched.
  - `atts_since`: Optional and supported by the http adapter only. Includes attachments only since specified revisions. Doesn’t includes attachments for specified revisions.
* `options.revs`: Each returned revision body will include its revision history as a `_revisions` property. Default is `false`.
* `options.attachments`: Include attachment data in the response. Default is `false`, resulting in only stubs being returned.
* `options.binary`: Return attachment data as Blobs/Buffers, instead of as base64-encoded strings. Default is `false`.
