/**
 * string.REPLACE implements eval function to replace part of a string.
 * Example:<code>
 *      register pigudfs.jar;
 *      A = load 'mydata' as (name);
 *      B = foreach A generate string.REPLACE(name, 'blabla', 'bla');
 *      dump B;
 *      </code>
 * The first argument is a string on which to perform the operation. The second argument
 * is treated as a regular expression. The third argument is the replacement string.
 * This is a wrapper around Java's String.replaceAll(String, String);
