/**
 * Compare 2 prosemirror nodes and check if it's greater, equal or less than the other node
 * based on the sort order.
 *
 * @param {Node} nodeA
 * @param {Node} nodeB
 * @returns {(1 | 0 | -1)}
 *
 * For Ascending order:
 *    1  -> NodeA > NodeB
 *    0  -> NodeA === NodeB
 *    -1 -> Node A < NodeB
 * For Descending order:
 *   1  -> NodeA < NodeB
 *   0  -> NodeA === NodeB
 *   -1 -> Node A > NodeB
 *
 * If either node is empty:
 * The empty node is always treated as lower priority,
 * irrespective of the order.
 *
 * If no order is provided the method defaults to Ascending order,
 * like a regular JS sort method.
