# Adds methods to help manipulate a subresource from its parent resource so
# that it's possible to do so from a static context (i.e. without a
# pre-existing collection of subresources on the parent).
#
# For example, a transfer gains the static methods for reversals so that the
# methods `.create_reversal`, `.retrieve_reversal`, `.update_reversal`,
# etc. all become available.
