		/* *** Instructions *** */
		//
		// some documentation states that when Mute() is called,
		// it will call .Quieter() on the passed in IVolume instance.
		// It should turn down the volume 10 notches at a time until
		// the current volume reaches 0.
		//
		// As a failsafe incase the volume knob breaks, the Mute()
		// method will only try to call .Quieter() at most 10 times.
		//
		// Verify that the Mute() function works as expected.
		//
		// For example, if the IVolume passed to Mute has its volume
		// set to 50 initially, then Mute() should call the Quieter
		// method exactly how many times?
		//
		// How many times is Quieter called if CurrentVolume already
		// returns "0"?
		//
		// Fill in these existing tests, and add more if you want.
