- G4RadioactiveDecay.cc::LoadDecayTable:line 931 create a decaytable for isomers not included in RDM database and assume 
  they all under go IT decay.
- G4RadioactiveDecay.cc: line 1434 after DoDecay() check if there is any secondary produced. Kill the track if not to 
  prevent it entering a infinite loop
- G4RadioactiveDecay.cc: line 1459. make sure the propertime is positive. negative case occures when the isomer is not in
  RDM database and its f-l is set to -1 by default.  
- G4NuclearDecayChannel.cc: Added initialisation to all three constructors: 
  halflifethreshold = 1e-6*second;
  applyICM = true;
  applyARM = true;

10 May 2010 F.Lei
- G4RadioactiveDecay.hh:line 264 corrected typo as pointed out by Luciano Pandola
- G4RadioactiveDecay.cc: insert a special treatment for K-40 beta decay at line 774 as suggested by Mauro Taiuti.
  This fixes bug #1068
  applied SetICM() SetARM() and SetHLThreshold() to a decay channel is created.
- G4NuclearDecayChannel.cc: line 396. Limit the shell index to < 7, as required by the ARM.
  line 329: change to use BreakUp rather than BreakItUp so to limit to one transition per step when ICM is applied (bug #1001)
  (Note: changes have also been made in 30/08/2008 to use the correct atomic shell index and to conserve energy atfer ARM, 
   these problems were pointed out by Andreas Zoglauer in the bug report).
- G4RadioactiveDecay.hh & G4NuclearDecayChannel.hh: added private member data "applyICM" "applyARM" "halflifethresold" 
  and their public Set methods SetICM(), SetARM() and SetHLThreshold().
- G4RadioactiveDecaymessenger: added the UICommands for SetICM, SETARM and SetHLThreshold.

	ii) use the correct shell index in appling ARM and switch on Auger 
	electron production
        iii) check the residual kinetic energy after ARM and add it to the atom
