- corrected docstring that was mistaken on what was returned
- updated pyproject.toml to ignore warnings that happened naturally in
networkx and that was blocking proper test execution (no way around that
this is code from networkx that triggered the warning)
- add a test case for the newly supported fusing topology
closes#499
- add an attribute fusable to False for the operations that should not be
explicitely fused from the original addition of GenericFunction
- add op_kind instance attribute to differentiate between TLU and memory
operations for GenericFunction
refs #600
