Research direction

Start with the getvalue(feature) function shown in issue #31 and inspect how feature.tags, layer.keys, and layer.values are structured and used elsewhere. Benchmark the current nested lookup, then define completion as a faster lookup that preserves the existing non-null return behavior and string lowercasing.
