lots of little stuff + silent config example

-removed Serial println debug
-fixed type in address example
-fixed address range comment
-utilized dataLength more properly in configureBuzzer
-created initial address variable in changeAddress example
-created silent configuration example to showcase config and set active reg functions.
-changed "acknowledged" to "connected" in print statements.

+  
+  It then turns the buzzer on and off using setBuzzerActiveReg() and off().
+  
+  Much like the classic "blink LED sketch" this will buzz
