D.5.6.7 abstractR

Procedure from library reszeta.lib (see reszeta_lib).

Usage:
abstractR(L);
L = list of rings

Assume:
L is output of resolution of singularities

Note:
currently only implemented for isolated surface singularities

Return:
list l
l[1]: intvec, where
l[1][i]=1 if the corresponding ring is a final chart
of non-embedded resolution
l[1][i]=0 otherwise
l[2]: intvec, where
l[2][i]=1 if the corresponding ring does not occur
in the non-embedded resolution
l[2][i]=0 otherwise
l[3]: list L
