Expects a function. The functions receives two arguments - two nodes to be compared. Return -1 or 1 (or any other different from -1). Default is:
function (a, b) { return this.get_text(a) > this.get_text(b) ? 1 : -1; }
Sorts the children of the specified node - this function is called automatically.
