//
// Tool to find and flag signal regions in ADC data using the
// algorithm developed for the 35t prototype TPC. An unpadded
// ROI starts for any signal above NSigmaStart sigma above the noise
// and continues until the level falls below NSigmaEnd sigma.
// NSigmaEnd was fixed to 1.0 in the original code.
//
// Configuration:
//   LogLevel    - usual log level
//   NoiseSigma  - Assumed noise level (sample units).
//                 If <=0, AdcChannelData::sampleNoise is used.
//   NSigmaStart - Level in sigma at which an unpadded signal starts.
//   NSigmaEnd   - Level in sigma at which an unpadded signal ends.
//   TicksBefore - Number of ticks to retain before unpadded region.
//   TicksAfter  - Number of ticks to retain after unpadded region.
//
// The output results holds:
//   nroi - # ROIs found
