This class simulates the functionality of the cathode LCT card. It is run by the MotherBoard and returns up to two CathodeLCTs. It can be run either in a test mode, where it is passed arrays of halfstrip and distrip times, or in normal mode where it determines the time and comparator information from the comparator digis.
The CathodeLCTs come in distrip and halfstrip flavors; they are sorted (from best to worst) as follows: 6/6H, 5/6H, 6/6D, 4/6H, 5/6D, 4/6D.
