Clean up nodes on destroy() #12
Description
If property nodes have no incoming or outgoing edges in the data flow graph, they should be removed from the graph when a reactive function that references them (as inputs or outputs) is destroy()ed.
To check:
- inputs with no outgoing edges
- inputs with no incoming edges
- output with no outgoing edges
- output with no incoming edges
When serializing the graph at the last unit test, this is what it looks like now:
{
"nodes": [
{ "id": "1" },
{"id": "2"},
{"id": "3" },
... all the way up to
{"id": "58" }
],
"links": [
{ "source": "57", "target": 56 },
{ "source": "58", "target": 56 }
]
}
