//   MExtractTime
//
//   Base class for the signal extractors, used the functions 
//   FindTimeHiGain() and FindTimeLoGain() to extract the signal and 
//   substract the pedestal value    
//
//   The following figure gives and example of possible inheritance trees. 
//   An extractor class can inherit from each of the following base classes:
//    - MExtractor
//    - MExtractTime
//    - MExtractTimeAndCharge
//
//Begin_Html
/*

*/
//End_Html
//
//   The following variables have to be set by the derived class and 
//   do not have defaults:
//   - fNumHiGainSamples
//   - fNumLoGainSamples
//   - fSqrtHiGainSamples
//   - fSqrtLoGainSamples
//
// Input Containers:
//   MRawEvtData
//   MRawRunHeader
//   MPedestalCam
//
// Output Containers:
//   MArrivalTimeCam
