This class contains the configuration information for a scanned analog input. Ideally each input channel could have it's own scan parameters. But they can't. The DAQ board can only perform one scan at a time (it's multiplexed). So what we do is configure one big scan (see ScannedAnalogInputCollection) and then chop up the data for each of the input channels. The big scan is as fast as the fastest scan and as long as the longest. Each channel is then reduced by either chopping the end off the data (as in the pmt) or binning the data up (the magnetometer).
