Throughput

To generate the throughput benchmark, we ported the benchmark available in this repository. Please, check this repository to see our changes.

Accuracy

To generate the accuracy benchmark, we have changed the whatlang-accuracy-benchmark to add support for Whichlang. Given that Whatlang supports more languages, we have used its FilterList feature to restrict its analysis to only languages that are supported in Whichlang. We also use the trigram method in Whatlang. Please, check this repository to see our changes.
