This change allows the user to set the log-level with homeSpan.setLogLevel() instead of needing to change in Settings.h. Next up: Update Example that introduces VERBOSE to instead use setLogLevel(). Consider adding an interactive 'L' command to change this during run-time.
Also, added "#pragma once" to every *.h file to prevent duplication of definitions. TO DO: Review all #include to ensure sanity across all files.
