public class FiveGrade
extends GradeBar

This UI components implements a continuous grading scale with "anchors" derived from the ITU-R five-grade impairment scale given in Recommendation ITU-R BS.562 as shown below.

Impairment                     Grade
Imperceptible                  5.0
Perceptible, but not annoying  4.0
Slightly annoying              3.0
Annoying                       2.0
Very annoying                  1.0

One decimal place is used.

This component is basically a simple extension to the generic GradeBar grading scale. This component simply predefines the limits of the scale, number of decimals and adjectives ("anchors").
