// Description:
// -----------
// Class StntupleExampleModule : adds user branch named "MyClcBlock" to STNTUPLE
//                           and fills it with CLC data
//
//
// comments for the users:
// -----------------------
// - to create a separate branch with the user data one starts from 
//   describing an object to be stored on this branch - equivalent of HBOOK's
//   "data block" (see Stntuple/obj/TCmuDataBlock.hh for the example)
// - `beginJob' entry point of the module calls AddDataBlock method
//    (this is a method of the base class StntupleModule) which creates 
//    the branch and appends it to the STNTUPLE tree
// - as CLC data block is a "standalone" block (filling it doesn't require
//   any information stored on other branches), it is filled with the event
//   data in InitStntupleModule::event and  `event' entry point of 
//   StntupleExampleModule doesn't do anything
// - the rest is being done automatically by the STNTUPLE infrastructure 
//   code
