toDual

toDual(d,f) -- given a 1 by n matrix f over a polynomial ring R and an integer d such that the d-th power of each variable is in the image of f, computes Hom(R/image f, E) , where E is the injective envelope of the coefficient field of R.

This function mimics the script <l_to_dual of Macaulay, and is probably going to be changed substantially.
