Answer the question: Why doesn't this function apply?
Possible input formats:
- FunctionName 6 3 2
- FunctionName (Sub tree1) (More (Trees of stuff))
- FunctionName words for subtrees
What to show:
- When features doesn't match
- When labels and cats doesn't match
Maybe start from the final devtree and recreate work so we can prioritize simpler diffs. We could even tell why a tree that was created wasn't included and if a subtree of what we asked for is missing, we can answer that.
