SoCounter — triggered integer counter

       This  engine  is a counter that outputs numbers, starting at a minimum value, increasing by a step value,
       and ending with a number that does not exceed the maximum value. It outputs the next number whenever  the
       trigger  input  is  touched.  When  the  maximum number is reached, it starts counting from the beginning
       again.

       At any time the counter can be reset to a specific value by setting the reset input field to that  value.
       The  next  time  the  counter  is triggered it will start counting from there. Note that the counter will
       always output numbers based on the min, max and step values, and setting the reset value does not  affect
       those  input  fields.  If  the reset value is not a legal counter value, the counter will still behave as
       though it is.

          If reset is greater than max, the counter is set to max.
          If reset is less than min, the counter is set to min.
          If reset is between steps, the counter is set to the lower step value.

     Each time a counting cycle is started, the syncOut  output  is  triggered.  This  output  can  be  used  to
     synchronize some other event with the counting cycle.
