Todo

Avoid use of unprotected std::cout: stringstream + MsgStream would be better

Todo

I get the feeling VerboseOutput is being abused here...

Todo

Looks like misuse of the verbose output flag

Todo

Isn't this if (m_VerboseOutput... redundant?

Todo

Isn't this if (m_VerboseOutput... redundant?

Todo

Is there no better way to detect unspecified masses than == 0? Final state photons should be 0
