Can we acquire digital inputs at the same time? #23

When we try it sets the sample rate to 0 and ceases to acquire.

Hmmm... The PCI 6110 has no clock on the digital lines. So that's why adding the lines to the same session leads to a sample rate of zero. The 6115, on the other hand, does have a 10 MHz clock on the digital lines.

So it seems like a bad idea to add too many extra features to SImpleMScanner. Then the software will start to depend too heavily on the properties of the board used for acquisition and everything will become more complicated. I think it's OK to use a digital line open and close the shutter, but nothing more than that is a good idea. We don't want to re-write ScanImage...
