meetings.updateCollection

Updates a collection of new Meetings, following the same rules for updates as a normal PUT would. IDs for update are expected to be set as the instanceId on each of the individual entities; it is these IDs which will be used to determine which entities will be updated. Because this method always returns a List of BulkOperationResponse, except in the case of an internal error, this API always returns an HTTP 200. For status on each individual operation, the BulkOperationResponse must be inspected.
