Modified ObserverLog: Singleton and both output to screen and internal Log.
- ObserverLog can now either be printed concurrently or later requested as
string (e.g. on exit as has been done before). This should ease debugging
Observer code.
- enable/disableLogging() (dis)activate printing to screen.
- ObserverLog is now a true singleton.
Details:
- Implemented helper class ObserverLog::Log which is returned as
boost::shared_ptr on addMessage() and can be streamed to.
- On dstor the logged message is appended with endl, placed into ObserverLog's
internal log and printed on screen if enableLogging().
- NOTE: streaming std::endl is not working, and not necessary.
