Updated comment on Interpolate to clarify behavior
/**
* Interpolate uses a collection of input/output samples that approximate a non-linear curve.
- * The output is the linear interpolation between the two nearest sample points.
- * It is used primarily for non-linear analog gauges such as temperature gauges using
