# This case sets the metadata on the inverse object as well as the
# document itself.

# @example Bind the documents.

# name.person = Person.new
#
# @param [ Hash ] options The binding options.
#
# @option options [ true, false ] :continue Continue binding the inverse.
# @option options [ true, false ] :binding Are we in build mode?
