Lack of testing module

I recently consumed this module while working on a project. However, since this repository lacked a robust testing and benchmarking module, I created one and I am now looking to share it.

The testing and benchmarking module I implemented ran the algorithm against English, Chinese, and Vietnamese words and phrases.

No files, tests, or entry points are named. Review the repository's current test and benchmark setup first, then determine how the proposed module should exercise the Aho-Corasick algorithm against English, Chinese, and Vietnamese words and phrases; done means the testing and benchmarking module is integrated and its results are reproducible.
