  Task transformation that changes operator costs. If the parent task assigns
  costs 'c' to an operator, its adjusted costs, depending on the value of the
  cost_type option, are:
 
    NORMAL:  c
    ONE:     1
    PLUSONE: 1, if all operators have cost 1 in the parent task, else c + 1
 
  Regardless of the cost_type value, axioms will always keep their original
  cost, which is 0 by default.
