Add option to provide A4 printable exports of base.scad
This should be done by (automatically?) creating enough scad files that intersect A4-sized cubes with the base and then export the projection as svg.
How can this be automated?
We can create a fixed number of files? Ugly. Create an external script written in python? php? This increases the dependencies for the user even more (python is only needed for the documentation publication atm, something that end users will not be required to do during building rosalind)
