Implementation of the Hierarchical Select API for the Book module.

Code

function hs_book_hierarchical_select_children($parent, $params) {

  // TRICKY: because the book form assumes that the value "0" corresponds to
  // the <top-level page> option (for creating a new menu item at the root
  // level) *AND* 0 is also a pseudo-value in the actual hierarchy (it
  // represents the root), we have to pretend in the code that -1 is the root
  // in the hierarchy instead of 0.
