This function creates a tropical cycle from a fan and a list of multiplicities. The multiplicities must be given in the same order as the maximal cones appear in the MaximalCones list.
i1 : F = fan {posHull matrix {{1},{0},{0}}, posHull matrix {{0},{1},{0}}, posHull matrix {{0},{0},{1}}, posHull matrix {{-1},{-1},{-1}}}
o1 = F
o1 : Fan

i2 : mult = {1,2,-3,1}
o2 = {1, 2, -3, 1}
o2 : List
|
i3 : tropicalCycle(F, mult)
o3 = TropicalCycle{...2...}
o3 : TropicalCycle

The object tropicalCycle is a method function.
