Procedures:

D.5.16.1 intersectionDiv		computes intersection form and genera of exceptional divisors (isolated singularities of surfaces)
D.5.16.2 spectralNeg		computes negative spectral numbers (isolated hypersurface singularity)
D.5.16.3 discrepancy		computes discrepancy of given resolution
D.5.16.4 zetaDL		computes Denef-Loeser zeta function (hypersurface singularity of dimension 2)
D.5.16.5 collectDiv		identify exceptional divisors in different charts (embedded and non-embedded case)
D.5.16.6 prepEmbDiv		prepare list of divisors (including components of strict transform, embedded case)
D.5.16.7 abstractR		pass from embedded to non-embedded resolution
D.5.16.8 computeV		multiplicities of divisors in pullback of volume form
D.5.16.9 computeN		multiplicities of divisors in total transform of resolution
