/* We encounter a bit of an issue here. Upon doing some research it is easily resolved
* by couchdb. Lets examine.
*
* Issue: We update the resource to the server, connection is lost, we try to delete the
* versions newer than the target version of the rollback. This fails. We now have
* zombie versions that will block future recreation of those versions as the IDs will
* be the same.
*
* Solution: "Updating existing documents requires setting the _rev member to the
* revision being updated. To delete a document set the _deleted member to true."
* http://wiki.apache.org/couchdb/HTTP_Bulk_Document_API.
*
* Example:
* {
* "docs": [
* {"_id": "0", "_rev": "1-62657917", "_deleted": true},
* {"_id": "1", "_rev": "1-2089673485", "integer": 2, "string": "2"},
* {"_id": "2", "_rev": "1-2063452834", "integer": 3, "string": "3"}
* ]
* }
*
* Implementation: So, we already have bulk document post support. We simply need to
* load the bulkdocument with the resource and the _id and _rev for each version we want
* to remove. We will also want to set the _deleted to true.

/* We encounter a bit of an issue here. Upon doing some research it is easily resolved
* by couchdb. Lets examine.
*
* Issue: We update the resource to the server, connection is lost, we try to delete the
* versions newer than the target version of the rollback. This fails. We now have
* zombie versions that will block future recreation of those versions as the IDs will
* be the same.
*
* Solution: "Updating existing documents requires setting the _rev member to the
* revision being updated. To delete a document set the _deleted member to true."
* http://wiki.apache.org/couchdb/HTTP_Bulk_Document_API.
*
* Example:
* {
* "docs": [
* {"_id": "0", "_rev": "1-62657917", "_deleted": true},
* {"_id": "1", "_rev": "1-2089673485", "integer": 2, "string": "2"},
* {"_id": "2", "_rev": "1-2063452834", "integer": 3, "string": "3"}
* ]
* }
*
* Implementation: So, we already have bulk document post support. We simply need to
* load the bulkdocument with the resource and the _id and _rev for each version we want
* to remove. We will also want to set the _deleted to true.
