  # Build a changeset class for the given resource class. The ChangeSet will
  # have fields to match the resource class given.
  #
  # To define a custom changeset with validations, use naming convention with "ChangeSet" appended to the end
  # of the resource class name. (e.g. for BookResource, name the change set BookResourceChangeSet)
  #
  # @example
  #   Hyrax::ChangeSet(Monograph)
  def self.ChangeSet(resource_class)
    klass = (resource_class.to_s + "ChangeSet").safe_constantize || Hyrax::ChangeSet
    Class.new(klass) do
