/** toHex
 *
 * A function (method) in Java to convert integers (type int) to a hex string.
 * This is one of my early contributions to Java. Back in Jan '96, the
 * java.lang.Integer class lacked a toHexString method. This was a common
 * request on Java newgroups and web pages of Java developers. Instead of
 * making a package, I just wrote a function that people could cut and paste
 * into their programs. Now that java.lang.Integer has a toHexString method,
 * this is obsolete
 *
 * @version 1.00 1996/Feb/02
 * Status: Obsolete. Use toHexString method of java.lang.integer.
