case class MetaRuleSetRow(ruleSuiteId: Int, ruleSuiteVersion: Int, ruleSetId: Int, ruleSetVersion: Int, columnFilter: String, ruleExpr: String) extends Product with Serializable
only one arg is supported without brackets etc.
Law: Each Rule generated must have a stable Id for the same column, the version used is the same as the RuleSet
The caller of withNameAndOrd must enforce this law to have stable and correctly evolving rules.
