stableTrees -- return the spanning trees that are stable

Synopsis

• Usage:

  stableTrees(th, Q)

• Inputs:
  • th, a list, of weights corresponding to each vertex
  • Q, an instance of the type ToricQuiver,
• Outputs:
  • L, a list, of lists, each representing the arrows that comprise a spanning tree that is stable with respect to the weight th
