//
// Pedestal additon service that obtains pedestals and their
// RMS values from a pedestal service.
// Pedestal noise is assigned using independent random Gaussian values
// for each tick with sigma = NoiseScale*RMS
// Parameters:
//    NoiseScale - The above noise scale. (<= 0 for no pedestal noise).
//    RandomSeed - Overrides NuRandomService if set nonzero.
//    LogLevel - (0=none, 1=init only, ...)
