* Purpose : Figlet font class
*
* Comments : phpFiglet is a php class to somewhat recreate the
* functionality provided by the original figlet program
* (http://www.figlet.org/). It does not (yet) support the
* more advanced features like kerning or smushing. It can
* use the same (flf2a) fonts as the original figlet program
* (see their website for more fonts).
*
* Usage : $phpFiglet = new phpFiglet();
*
* if ($phpFiglet->loadFont("fonts/standard.flf")) {
* $phpFiglet->display("Hello World");
* } else {
* trigger_error("Could not load font file");
* }
