I have plans to fix them, so:
1. Name.  Rename subresultantVector and subResultantList to
subresultants.  I don't think same same will cause trouble, because
they are both not exposed by default, and users of this function
already explicitly import SubResultantPackage.

2. Order. The traditional order of subresultants is ascending, starting
from 0.  I plan to make the return type of "subresultants" to be
IndexedVector(0, UP).

3. Size. Traditionally, subresultants(p,q) has min(degree p, degree q)
members, it doesn't include p or q.  I plan to make the size of
"subresultants" to be min(degree p, degree q), but then in
monomialIntegrate1$INTTR, it has to be repalced by Subresultatns PRS,
because of Theorem 2.5.1 of Symbolics Integration, clause (ii).
Or we have to extend the definition of "subresultants" to include p or q.

Opinions?
