>>> from phylox import DiNetwork
>>> from phylox.classes.dinetwork import is_stack_free
>>> network = DiNetwork(
...     edges=[(0,1),(1,2),(1,3),(2,4),(3,5),(2,5),(3,4),(4,6),(5,7)],
... )
>>> is_stack_free(network)
True

>>> network = DiNetwork(
...     edges=[(0,1),(1,2),(1,3),(2,3),(3,5),(2,4),(4,5),(4,6),(5,7)],
... )
>>> is_stack_free(network)
False
