/**
 * DisjointNode.
 *
 * The DisjointNode class represents the disjoint set node. It uses a pointer to the
 * next parent node and a rank attribute used to add the little tree to the bigger.
 * The trees with just one element have a rank of 0.
 * Using rank the execution time for operations makeSet, union, and find is of O(log n).
 * Rank is used instead of depth.
