22  * <li>boolean ex : if true it checks if the String exclude equals the current
23  * value, if equal this value will be skipped (no HTML
24  * generated for this item)</li>
25  * <li>String exclude : see above</li>
26  * <li>boolean moreValues : if true it will make a list of items.</li>
27  * <li>boolean moredouble : if true it will make a paired list of items.
28  * (first item = VALUE second item=NAME)</li>

30  * <li>boolean vertical : if true the various checkboxes are seperated with &lt;brk /&gt; tags.</li>
