# Deletes multiple objects or containers with a single request.
#
# To delete objects from a single container, +container+ may be provided
# and +object_names+ should be an Array of object names within the container.
#
# To delete objects from multiple containers or delete containers,
# +container+ should be +nil+ and all +object_names+ should be prefixed with a container name.
#
# Containers must be empty when deleted. +object_names+ are processed in the order given,
# so objects within a container should be listed first to empty the container.
#
# Up to 10,000 objects may be deleted in a single request.
# The server will respond with +200 OK+ for all requests.
# +response.body+ must be inspected for actual results.
#
# @example Delete objects from a container
# object_names = ['object', 'another/object']
# conn.delete_multiple_objects('my_container', object_names)
#
# @example Delete objects from multiple containers
# object_names = ['container_a/object', 'container_b/object']
# conn.delete_multiple_objects(nil, object_names)
#
# @example Delete a container and all it's objects
# object_names = ['my_container/object_a', 'my_container/object_b', 'my_container']
# conn.delete_multiple_objects(nil, object_names)
#
# @param container [String,nil] Name of container.
# @param object_names [Array<String>] Object names to be deleted.
# @param options [Hash] Additional request headers.
#
# @return [Excon::Response]
# * body [Hash] - Results of the operation.
# * "Number Not Found" [Integer] - Number of missing objects or containers.
# * "Response Status" [String] - Response code for the subrequest of the last failed operation.
# * "Errors" [Array<object_name, response_status>]
# * object_name [String] - Object that generated an error when the delete was attempted.
# * response_status [String] - Response status from the subrequest for object_name.
# * "Number Deleted" [Integer] - Number of objects or containers deleted.
# * "Response Body" [String] - Response body for "Response Status".
