Selecting all children of a given taxonomy term can be a pain. This module makes it easier to do this, by maintaining a complete list of edges for each term using the adjecency matrix graph theory.

function taxonomy_edge_get_top_tid($tid) {
  $tids = taxonomy_edge_get_top_tids(array(
    $tid,
  ));
  return reset($tids);
