Compute global sections of an ideal sheaf with support on the exceptional divisors on W' (where W'->W is the last computed resolution) specifying a power for each exceptional divisor (identified by values of the Villamayor function).

A list of pairs (VFN, n), where VFN is a value of the Villamayor function which was attained on the blowing up center that defined the blowing up in which the exceptional divisor in question was created, and n is the power to which the corresponding factor of the ideal sheaf should be risen.
The list of generators of the ideal of global sections on W.
