added 4up
FourLateral is for ordered cards, it lays out cards in a 4up format but
stacks each sub page down through the stack first instead of simply
laying out 1-4 on the first page and 5-8 on the second etc.

See the test documents for how it works. -4U.pdf files are the output.

To run: java -cp itext-2.0.4.jar:<path to classfile> FourLatteral <input.pdf>
move 4up and create layup directory for layout utilities
