+/**
+ * Escapes the characters in a <code>String</code> using JavaScript String rules.
+ * <p/>
+ * Escapes any values it finds into their JavaScript String form.
+ * Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
+ * <p/>
+ * So a tab becomes the characters <code>'\\'</code> and
+ * <code>'t'</code>.
+ * <p/>
+ * The only difference between Java strings and JavaScript strings
+ * is that in JavaScript, a single quote must be escaped.
+ * <p/>
+ * Example:
+ * <pre>
+ * input string: He didn't say, "Stop!"
+ * output string: He didn\'t say, \"Stop!\"
+ * </pre>
+ *
