union -- computes the union of two posets

Synopsis

Usage:
R = union(P, Q)
R = P + Q
Inputs:
- P, an object of class Poset
- Q, an object of class Poset
Outputs:
- R, an object of class Poset, the union of P and Q

Description

The union of two posets is the poset induced by the union of the ground sets and the covering relations.

i1 : union(chain 3, poset {{1,4},{4,5},{5,3}})

o1 = Poset{cache => CacheTable{}                                }
           GroundSet => {1, 2, 3, 4, 5}
           RelationMatrix => | 1 1 1 1 1 |
                             | 0 1 1 0 0 |
                             | 0 0 1 0 0 |
                             | 0 0 1 1 1 |
                             | 0 0 1 0 1 |
           Relations => {{1, 2}, {2, 3}, {1, 4}, {4, 5}, {5, 3}}
