def or_evaluator(conditions, leaf_evaluator)
  # Evaluates an array of conditions as if the evaluator had been applied
  # to each entry and the results OR-ed together.
  #
  # conditions - Array of conditions ex: [operand_1, operand_2]
  #
  # leaf_evaluator - Function which will be called to evaluate leaf condition values.
  #
  # Returns boolean if the user attributes match/don't match the given conditions,
  #         nil if the user attributes and conditions can't be evaluated.
