RelativePositioning#position_between

This method takes two integer values (positions) and
calculates the position between them. The range is huge as
the maximum integer value is 2147483647. We are incrementing position by IDEAL_DISTANCE * 2 every time
when we have enough space. If distance is less then IDEAL_DISTANCE we are calculating an average number
