    *  The ubiquitous, standard log levels to use are:  info, warning, error, critical
    *  info      - I'm telling you, but you probably won't bother reading anyway.
    *  warning   - You should know about this. I'm telling you now, so you can's sue me later.
    *  error     - Something failed, but the world is not going to end.
    *  critical  - Something failed, and it hit you right in the eye. It really hurts, you have to do something.
    *  Other log levels are for special uses and may have side effects that you don't know about,
    *  and they may not work like expected under the specific conditions they run in... don't use them.

      *  This is the One Function you must implement. Everything else is optional or bull.
      *  It must be possible to call this function in presence and in absence of GUI without crashing the application.
      *  It is not necessary to provide any actual output at all times, but it must be 100% safe to call this function at all times.
      *  You may not throw from this function, it must return in finite time, and it must not call logging functions (to prevent infinite recursion).
      *  Other than that, you can do anything you want with the log messages that you receive.
