ChordalNetNode -- a node of a chordal network

Description

This type represents a node of a chordal network.

Each node of the network has the following properties:

• equations: a set of polynomials F
• inequations: a set of polynomials H
• rank: a variable of the polynomial ring
• label: a string that uniquely identifies the node (only needed for visualization)

These properties can be accessed with the functions: gens, ineqs, rank, label

The incoming/outgoing arcs of a node can be obtained as

• parents -- get the outgoing arcs
• children -- get the incoming arcs
