<h1>Multi-columns</h1>
This example is a variant of the previous one showing how to lay the text across multiple
columns.

<a href='tuto4.php' target='_blank' class='demo'>[Demo]</a>
The key method used is <a href='../doc/acceptpagebreak.htm'>AcceptPageBreak()</a>. It allows to accept or not an automatic page
break. By refusing it and altering the margin and current position, the desired column layout
is achieved.
 
For the rest, not many changes; two properties have been added to the class to save the current
column number and the position where columns begin, and the MultiCell() call specifies a
6 centimeter width.
