Verbose logging table

You can monitor console outputs by enabling the verbose mode and setting a verbose level. In most cases it's helpful for debugging.

Myo myo = new Myo(this);
myo.setVerbose(true);      // Default level: 1
myo.setVerboseLevel(2);    // Levels: [1, 2, 3]
// myo.setVerbose(false);  // Disable logging
