* Calculates shifts (offsets) for every item that needs to be moved
* @param {number} originalIndex Draggable item source index
* @param {number} moveToIndex New index where is currently draggable item should appear
* @param {boolean} shiftForward is shifting to forward position
* @sample
* We have three nodes @ DOM:
* Item1 has position {top1, left1, bottom1, right1}
* Item2 has position {top2, left2, bottom2, right2}
* Item3 has position {top3, left3, bottom3, right3}
* When we're dragging Item2 to replace Item1 we have:
* originalIndex: 1
* moveToIndex: 0
* shiftForward: false
* Item2's placeholder should be animated to Item1's position
* Item1's container should be animated to Item2's position
* To be sure that new position is correct we should relay our calculations on moving direction:
* When we're dragging item to the top, another shifting items should be visually moved to difference of their bottom positions (it means a height of current item, but with its margins)
* When we're dragging item to the bottom, another shifting items should be visually moved to difference of their top positions (it means a height of current item, but with its margins)
* Same logic exists for horizontals sortable lists and all calculations are based on differences between left or right positions
