Scaler

A trait for defining a new family of scaling functions scalingType: a ScalingType Enum for the scaling name args: A case class containing the args needed to define scaling and inverse scaling functions scale: The scaling function descale: The inverse scaling function

To add a new family of scaling functions: Add an entry to the scalingType enum, define a Case class extending Scaler, and add a case statement to both the Scaler and ScalerMetaData case classes
