-  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.
-   move(angle) - Sequence of attach(0), write(angle),
-                   With DEACTIVATE_SERVOS_AFTER_MOVE wait SERVO_DELAY and detach.
+ *
+ * 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 sequence used to seize timers is defined in timers.h
