I think the way it's supposed to work is to set app.LOG to 'true' if you want to see logs from app.consoleLog(), and set it to 'false' if you don't. You can change this anywhere in your code to go back and forth between the two choices. To be safest, you might want to refer to it as window.app.LOG, and then log things with window.app.consoleLog().
app.consoleLog should act just like console.log, except that it will be a no-op if app.LOG is not 'true'.
Does that help?
