Base Template LowerUpperMagnitudeOfPropertyRange

LowerUpperMagnitudeOfPropertyRange is a template for expressing the extent of a property range, in terms of maximum and minimum values on a scale.

LowerUpperMagnitudeOfPropertyRange(a, b, c, d) means that a is a property range, b is a scale, and c and d are numbers, and that a has c and d as, respectively, lower and upper bounds, as measured on the scale b.
