/**
* Links and flowing text
*
* This tutorial explains how to insert links (internal and external) and shows
* a new text writing mode. It also contains a rudimentary HTML parser.
* The new method to print text is Write(). It is very close to MultiCell();
* the differences are: The end of line is at the right margin and the next line
* begins at the left one. The current position moves at the end of the text.
* So it allows to write a chunk of text, alter the font style, then continue from
* the exact place we left it. On the other hand, you cannot full justify it.
*
* The method is used on the first page to put a link pointing to the second one.
* The beginning of the sentence is written in regular style, then we switch to
* underline and finish it. The link is created with AddLink(), which returns a
* link identifier. The identifier is passed as third parameter of Write(). Once
* the second page is created, we use SetLink() to make the link point to the
* beginning of the current page.
*
* Then we put an image with a link on it. An external link points to an URL
* (HTTP, mailto...). The URL is simply passed as last parameter of Image().
*
* Finally, the left margin is moved after the image with SetLeftMargin() and some
* text in XML format is output.
* Recognized tags are <B>, <I>, <U>, <A> and <BR>; the others are ignored.
