Debug Level Not Showing Up

[vpetreski]

Hi, I tried many things but DEBUG level is not shown for some reason. My configuration:

//Logger.useDefaults();
Logger.useDefaults({
    defaultLevel: Logger.DEBUG,
    formatter: function (messages, context) {
        messages.unshift(new Date().toUTCString())
    }
});

Logger.setLevel(Logger.DEBUG);

// Only log WARN and ERROR messages.
//Logger.setLevel(Logger.WARN);
//Logger.debug("Donut machine is out of pink ones");  // Not a peep.
//Logger.warn("Asteroid detected!");  // Logs "Asteroid detected!", best do something about that!

// Ah, you know what, I'm sick of all these messages.
// But I want to see them again later
//var oldLevel = Logger.getLevel();
//Logger.setLevel(Logger.OFF);
//Logger.error("Hull breach on decks 5 through to 41!");  // ...

// Actually, maybe those logs were quite useful...
//Logger.setLevel(oldLevel);

Logger.debug("I'm a debug message!");
Logger.info("OMG! Check this window out!", window);
Logger.warn("Purple Alert! Purple Alert!");
Logger.error("HOLY SHI... no carrier.");

Logger.debug("XXXXXXXX");
Logger.debug("YYYYYYYY");

// Start timing something
Logger.time('self destruct sequence');

// ... Some time passes ...

// Stop timing something.
Logger.timeEnd('self destruct sequence'); // logs: 'self destruct sequence: XXXms'.

I'm guessing this is a dupe of #61; if so I would very much appreciate a PR against the README which warns other users about this issue.

Thanks!
