# DivisorClassRepresentativeM0nbar -- class implementing divisors on the moduli space of stable n-pointed genus zero curves

## Description

This class represents divisor classes in $NS^1(\bar{M}_{0,n})$. A divisor class is just a linear combination of the boundary divisors $\delta_I$.

 i1 : H=new HashTable from { {{1,3},1}, {{1,4},1} }; i2 : divisorClassRepresentativeM0nbar(6,H) o2 = DivisorClassRepresentativeM0nbar{DivisorExpression => HashTable{{1, 3} => 1}} {1, 4} => 1 NumberOfMarkedPoints => 6 o2 : DivisorClassRepresentativeM0nbar

## For the programmer

The object DivisorClassRepresentativeM0nbar is a type, with ancestor classes HashTable < Thing.
