/** \class THcConfigEvtHandler
    \ingroup base

  Event handler for Hall C prestart config event.  Type 125

  To use as a plugin with your own modifications, you can do this in
  your analysis script

  gHaEvtHandlers->Add (new THcConfigEvtHandler("hallcpre","for evtype 125"));

  As config data is found, Hall C parameters will be created to hold the configuration
  data.

  All the configuation data can also be printed out with the PrintConfig method
