def set_inflection(association, options)
  return if options[:collection].nil?
  # since RLM has an irregular API we have to adjust the inflections
  # so we can have children collections that do not match the parents
  # i.e.
  # <DETAILS>
  #   <LINE>
  # instead of default behavior
  # <DETAILS>
  #   <DETAIL>
  #
  # the code below dynamically adjusts active_support inflections
  # here is a basic example
  #
  # ActiveSupport::Inflector.inflections do |inflect|
  #   inflect.singular 'DETAILS', 'LINE'
  # end
