	##	FUNCTIONS:
	##	> parser($feed, $max, $print)
	##	> core_beginElement($parser, $tag)
	##	> core_endElement($parser, $tag)
	##	> core_characterData($parser, $data)
	##	> core_loadFeed()
	##---------------------------------------------------------------------
	##	KNOWN BUGS:
	##	
	##---------------------------------------------------------------------
	##	NOTES:
	##	> It's possible to switch between direct output (script prints
	##	> immediately) or array output. You can also set how much item you
	##	> want to print. If you need/want to modify HTML used in direct
	##	> output, find lines 144 - 151.
	##---------------------------------------------------------------------
	##	USAGE:
	##	> $feed = 'http://www.domain.com/feed.xml';
	##	> $max_items = 5;
	##	> $rss = new mod_rss();
	##	>
	##	> // for direcet output
	##	> $direct_output = true;
	##	> $rss->parser($feed, $max_items, $direct_output);
	##	>
	##	> // for array output
	##	> $direct_output = false;
	##	> $rss_array = $rss->parser($feed, $max_items, $direct_output);
	##---------------------------------------------------------------------
	##	ARRAY OUTPUT:
	##	> $var[$row]['title'] - title
	##	> $var[$row]['description'] - description
	##	> $var[$row]['link'] - link
	##	> $var[$row]['date'] - date
