Message:

Log() and eLog() are prepended by a DoLog()/DoeLog() construct.

• Most of the run time (95%) is spent on verbosity that it is discarded anyway due to a low verbosity setting. However, the operator << is evaluated from the right-hand side, hence the whole message is constructed and then thrown away.
• DoLog() and DoeLog() are new functions that check the verbosity beforehand and are used as follows: DoLog(2) && (Log() << verbose(2) << "message" << endl);
