## Resolving properties
Current matching does:
1. Find exact name match, with exact state match.
If found return
1. Find exact class match, with exact state match.
If found return
1. Find fuzzy name match, with fuzzy state.
If found is not root node, return
1. Find fuzzy class match, with fuzzy state.
return
It tries to find the longest match down the dependency tree.
