  MODULE: OB_ERPDETECT.H:  declarations for the ERP-Detector-Object
  Author: Chris Veigl

  The ERP-Detector - Object can record a signal and average a given number of trials
  (recording phase). Then, the signal stream is compared to this pattern and the 
  similarity (%) to the pattern is presented to the object's output port (detection phase)
