/* Filemanager class
*
* What is it?
* This class reads a directory and collects all data on files and directories.
*
* AUTHOR:
* Johan Adriaans <gnarf@izi-games.com>
*
* USAGE:
* $base_dir = "/";
* $sub_dir = "etc/";
* $dir = new fileman($base_dir, $sub_dir);
* foreach($dir->directories as $directory) print $directory->name . "<BR>";
* foreach($dir->files as $file) print $file->name . "<BR>";
*
* STRUCTURE VIEW:
* $base_dir = "/";
* $sub_dir = "etc/";
* $dir = new fileman($base_dir, $sub_dir);
* print "<PRE>";
* foreach($dir->directories as $directory) print_r($directory);
* foreach($dir->files as $file) print_r($file);
* print "</PRE>";
