/* A schedule (sub)tree.
*
* The leaves of a tree are not explicitly represented inside
* the isl_schedule_tree. If a tree consists of only a leaf,
* then it is equal to the static object isl_schedule_tree_empty.
*
* ctx may be NULL if type is isl_schedule_node_leaf.
* In this case, ref has a negative value.
*
* The "band" field is valid when type is isl_schedule_node_band.
* The "context" field is valid when type is isl_schedule_node_context
* and represents constraints on the flat product of the outer band nodes,
* possibly introducing additional parameters.
* The "domain" field is valid when type is isl_schedule_node_domain
* and introduces the statement instances scheduled by the tree.
*
* The "contraction" and "expansion" fields are valid when type
* is isl_schedule_node_expansion.
* "expansion" expands the reaching domain elements to one or more
* domain elements for the subtree.
* "contraction" maps these elements back to the corresponding
* reaching domain element. It does not involve any domain constraints.
*
* The "extension" field is valid when the is isl_schedule_node_extension
* maps outer schedule dimenions (the flat product of the outer band nodes)
* to additional iteration domains.
*
* The "filter" field is valid when type is isl_schedule_node_filter
* and represents the statement instances selected by the node.
*
* The "guard" field is valid when type is isl_schedule_node_guard
* and represents constraints on the flat product of the outer band nodes
* that need to be enforced by the outer nodes in the generated AST.
*
* The "mark" field is valid when type is isl_schedule_node_mark and
* identifies the mark.
*
* The "children" field is valid for all types except
* isl_schedule_node_leaf. This field is NULL if there are
* no children (except for the implicit leaves).
*
* anchored is set if the node or any of its descendants depends
* on its position in the schedule tree.
