org.jmol.util.StringXBuilder

public class StringXBuilder
extends java.lang.Object

Interesting thing here is that JavaScript is 3x faster than Java in handling strings. Java StringXBuilder is final, unfortunately. I guess they weren't thinking about Java2Script! The reason we have to do this that several overloaded append methods is WAY too expensive
