The example demonstrates usage of `NumberRange` process. The NumberRange let you define custom name for a range. Like in above example, we define charity amount less than \$20 is Low, from 20 to less than 50 is Medium and higher or equal to \$50 is High.

The NumberRange is normally used with Group process as above example showing.
