Simple ANSI colors class for terminal code for JVM written in Scala and Java (two implementations)

Ansi.java

package org.tempura.console.util;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

/**
 * Usage:
 * <li>String msg = Ansi.Red.and(Ansi.BgYellow).format("Hello %s", name)</li>
 * <li>String msg = Ansi.Blink.colorize("BOOM!")</li>
 * 
 * Or, if you are adverse to that, you can use the constants directly:
 * <li>String msg = new Ansi(Ansi.ITALIC, Ansi.GREEN).format("Green money")</li>
 * Or, even:
 * <li>String msg = Ansi.BLUE + "scientific"</li>
 * 
 * NOTE: Nothing stops you from combining multiple FG colors or BG colors, 
 *       but only the last one will display.

Amazing code, it helps me a lot and save me bunch of time digging google.
