threeVertexQuiver -- make a toric quiver on underlying graph with three vertices and a specified number of edges between each

Synopsis

Usage:

threeVertexQuiver E
Inputs:
- E, a list, number of edges between each pair of vertices
Optional inputs:
- Flow (missing documentation) => ..., default value Canonical, specify what form of flow to use. This input can be either a string with values Canonical or Random, or else a list of integer values.
Outputs:
- Q, an instance of the type ToricQuiver,
