D.5.9.4 zetaDL

Assume:

L is the output of resolution of singularities

Compute:

local Denef-Loeser zeta function, if string s1 is present and has the value 'local'; global Denef-Loeser zeta function otherwise
if string s1 or s2 has the value "A", additionally the characteristic polynomial of the monodromy is computed

Return:

list l
if a is not present:
l[1]: string specifying the top. zeta function
l[2]: string specifying characteristic polynomial of monodromy, if "A" was specified
if a is present:
l[1]: string specifying the top. zeta function
l[2]: list ast,
ast[1]=chi(Ei^*)
ast[2]=chi(Eij^*)
ast[3]=chi(Eijk^*)
l[3]: intvec nu of multiplicites as needed in computation of zeta function
l[4]: intvec N of multiplicities as needed in compuation of zeta function
l[5]: string specifying characteristic polynomial of monodromy, if "A" was specified
