Subject: Clock settings in daisy chain DAQ 

Here is the full version of the program with clock daisy-chaining. Before switching to the external clock, it checks if the clock really is there (by reading an internal scaler), and only then enables it. Note that the code also works without clock daisy-chaining. But without clock daisy-chaining your have some 400 ps time resolution between boards, and with clock daisy-chaining you get some 60 ps.
