/**
 * A helper class to manage drag-and-drop operations for ranges in a list.
 * This class encapsulates all the logic needed to handle pointer events,
 * detect collisions, and move ranges visually and logically within a container.
 *
 * @example
 * // Initialize the helper with a callback to handle the range movement
 * const helper = new RangeDragDropHelper((sourceIndex, targetIndex) => {
 *     console.log(`Move range from ${sourceIndex} to ${targetIndex}`);
 * });
 *
 * // Attach event listeners to a range container
 * <div
 *   onPointerDown={(event) => helper.onPointerDown(event, rangeIndex, isTouchEvent)}
 * />
 *
 * @export
