case class UpdateLongBy(key: ADKey, delta: Long) extends Modification with Product with Serializable
If the key exists in the tree, add delta to its value, fail if the result is negative, and remove the key if the result is equal to 0. If the key does not exist in the tree, treat it as if its value is 0: insert the key with value delta if delta is positive, fail if delta is negative, and do nothing if delta is 0.

Update functions takes Option[oldValue] and return Try[Option[newValue]] For example: Insert: None => Success(Some(newValue)), but Some(oldValue) => Failure() Update: Some(oldValue) => Success(Some(newValue)) Delete: Some(oldValue) => Success(None), but None => Failure() ConditionalUpdate: Some(oldValue) => Success(Some(newValue)) or Failure(), depending on whether oldValue satisfied some desired conditions
