Describe the bug
The mapping from integers to directions in the manual page for the data router is not correct.

To Reproduce
Steps to reproduce the behavior:

1. Build a data input machine, a data router, and a receiver for data.
2. Connect the data input machine to one of the sides of the data router.
3. Connect the top of the data router to the receiver.
4. Shift-right-click the data router with a hammer until it reads d.
5. In the data input machine, send a packet with d set to the integer value zero. Then again with the value one.

Expected behavior
I expect the receiver to receive a packet when d is zero, because the manual says zero corresponds to the top face. Actually, the receiver receives the packet when d is one.
