// Service that adds stuck bits to ADCs.
//
// FCL parameters:
//    StuckBitsProbabilitiesFname - Input file name
//    StuckBitsOverflowProbHistoName  - Name of histogram with overflow probablilities
//    StuckBitsUnderflowProbHistoName - Name of histogram with underflow probablilities
//    RandomSeed - Overrides NuRandomService if set nonzero.
//    LogLevel - (0=none, 1=init only, ...)
