History
Werner Almesberger eac6e3c70b atben/README-PCB, atusb/README-PCB: various minor clarifications 
- README-PCB: added imperial units for board thickness
- README-PCB: changed surface finish recommendation to prefer ENIG more
  strongly
- README-PCB: removed instructions for Gerber file generation from
  "interpretation of files section"
- README-PCB: mention common coordinate system origin

README 

PCB manufacturing:

- do not print PCB edges on front/back copper
- do not print component values on silk screen
- note that the transceiver is "upside down"
- the center (!) of the board edge line marks the true board edge, e.g.,

                             Edge line (5 mil)
