Turns on extensive logging of objects and events. Logs all events. This creates large log files and slows the program down.

A related routine is <A HREF="../Profiling/PetscLogDefaultBegin.html#PetscLogDefaultBegin">PetscLogDefaultBegin</A>() (with the options key -log), which is
intended for production runs since it logs only flop rates and object
creation (and shouldn't significantly slow the programs).
