Fill free to control which information will be showed depending on how deep you need the information to be showed. Are you developing? Set output level to verbose and see everything that is happening inside your functions. Set information messages level to users, or don't show a message at all if you want best performance.
Do you want messages to be output to a log file? Just change the Output.place to the desired output path!
Check example.m to see how it works.
