Modified by William Eriau - inmagnaveritas[at]gmail.com - fixed positioning problem when using doctype 
Modified by Pascal Hennig - added german as second language; 
							made script flexible, so you can use parameters to disable or allow the Past. Just call lcs(this, true) to disable the Past.
							Choose between Monday and Sunday as your starting day.
