+  Switch statement  with serial input
+ 
+ Demonstrates the use of a switch statement.  The switch
+ statement allows you to choose from among a set of discrete values
+ of a variable.  It's like a series of if statements.
+ 
+ To see this sketch in action, open the Serial monitor and send any character.
+ The characters a, b, c, d, and e, will turn on LEDs.  Any other character will turn
+ the LEDs off.
+ 
+ The circuit:
+ * 5 LEDs attached to digital pins 2 through 6
