MergeTree class has no attribute node

[pattonw]

MergeTree defined in "lsd/merge_tree.pyx" seems to inherit from nx.DiGraph and tries to look up nodes via self.node[node_id].

I think all of these calls should be changed to self.nodes[node_id].
networkx also isn't in the requirements file so maybe its just a versioning issue.

Ran into this error when using agglomerate_in_block.

can confirm, agglomerate_in_block works with networkx==2.2, does not with 2.5

I think it makes most sense to move post-processing scripts to funlib.segment or another repo and keep this repo strictly for lsds. we can pin networkx then.
