/* An isl_schedule_node points to a particular location in a schedule tree.
*
* "schedule" is the schedule that the node is pointing to.
* "ancestors" is a list of the n ancestors of the node
* that is being pointed to.
* The first ancestor is the root of "schedule", while the last ancestor
* is the parent of the specified location.
* "child_pos" is an array of child positions of the same length as "ancestors",
* where ancestor i (i > 0) appears in child_pos[i - 1] of ancestor i - 1 and
* "tree" appears in child_pos[n - 1] of ancestor n - 1.
* "tree" is the subtree at the specified location.
*
* Note that the same isl_schedule_tree object may appear several times
* in a schedule tree and therefore does not uniquely identify a position
* in the schedule tree.
