Class: QuantityValue
A quantity with a numeric value and unit of measurement. Used for all measurement values in assays. Optionally records what kind of central value this is (mean, median, single measurement), the reported variability around it (SD, SEM, confidence interval, range), and the number of subjects or replicates behind it. Keeping variability separate from the central value lets downstream analyses use each independently.
