divisor -- creates a Divisor

Description

Creates a Divisor from a given List of coordinates and a surface.

i1 : X = quadricSurface(ZZ/101[x,y,z,w]);

i2 : D = divisor({3,2},X)

o2 = {3, 2}

o2 : Divisor

i3 : X = cubicSurface(ZZ/101[x,y,z,w]);

i4 : D = divisor({3,1,1,1,1,1,1},X)

o4 = {3, 1, 1, 1, 1, 1, 1}

o4 : Divisor

Usage:

D = divisor(L,X)
Inputs:
- L, a list, of coordinate
- X, an instance of the type QuarticSurfaceRational
Outputs:
- D, an instance of the type Divisor

i5 : X = quarticSurfaceRational(ZZ/101[x,y,z,w]);

i6 : D = divisor(splice{3,9:1},X)

o6 = {3, 1, 1, 1, 1, 1, 1, 1, 1, 1}

o6 : Divisor
