// add values to the trie
trie.add('/foo/bar', yourValue1);
trie.add('/foo/:p1/bar/:p2', yourValue2);

// path matching
trie.match('/foo/bar');
// {
//   value: yourValue1,
//   params: {}
// }

// path matching (with parameters)
trie.match('/foo/10/bar/20');
// {
//   value: yourValue2,
//   params: {p1: 10, p2: 20}
// }

// if not matched
trie.match('/foo/bar/baz');
// undefined
