docs: Gets the ruleType value for this Rule.
  
  @return ruleType   * Rule type is used to determine how to group rule item groups
  and rule items inside rule item
  group. Currently, conjunctive normal form (AND of
  ORs) is only supported for
  ExpressionRuleUserList. If no ruleType is specified,
  it will be treated as disjunctive normal
  form (OR of ANDs), namely rule item groups are ORed
  together and inside each rule item group,
  rule items are ANDed together.
