+
+ A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
+ The servos are pulsed in the background using the value most recently written using the write() method
+
+ Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
+ Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
+
+ The methods are:
+
+ Servo - Class for manipulating servo motors connected to Arduino pins.
+
+ attach(pin )  - Attaches a servo motor to an i/o pin.
+ attach(pin, min, max  ) - Attaches to a pin setting min and max values in microseconds
+ default min is 544, max is 2400
+
+ write()     - Sets the servo angle in degrees.  (invalid angle that is valid as pulse in microseconds is treated as microseconds)
+ writeMicroseconds() - Sets the servo pulse width in microseconds
+ read()      - Gets the last written servo pulse width as an angle between 0 and 180.
+ readMicroseconds()   - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
+ attached()  - Returns true if there is a servo attached.
+ detach()    - Stops an attached servos from pulsing its i/o pin.
