case class PositionMapper(originalText: String, substitutedText: String, substitutions: List[Substitution]) extends Product with Serializable
Maps positions between original SQL text and substituted SQL text using sparse ranges.
This implementation uses O(k) space and O(log k) lookup time where k = number of substitutions.
