public class CommaSeparated
extends Object

CommaSeparated provides an easy way to build comma separated lists within a String or a StringBuilder. A comma separated list consists of a beginning string, an ending string, and any number (including zero) of elements in between them. If more than one element is added, then a comma and a space are injected in between them.
