[Jenne, Sheila, Matt]

On our way to trying for some low noise, we went through the CoilDrivers state.  But, somehow there was some buggy code in there that it was only trying to switch the UL coil of all the optics ('PRM', 'PR2', 'SRM', 'SR2', 'BS', 'ETMY', 'ETMX', 'ITMY', 'ITMX') over and over again, and never going to any other coils.  After a few minutes of this, we lost lock.  I don't know that I can prove that that's why we lost it, but we lost lock on this state yesterday also, and certainly having 3 coils one way, and one coil continually going between states 1 and 3 isn't helping keep us locked. Code fixed, we'll try it again next lock.
