var _trie = new Trie();

_trie.push("Hello", {"id":1, "txt":"Hello World"});
_trie.push("Hilly", {"id":2, "txt":"Hello Hilly"});
_trie.push("Hello, brother", {"id":3, "txt":"Whats up?"});
_trie.push("Hello, bob", {"id":4, "txt":"Hey dude"});


Query 1:
_trie.wildcard("H*ll.", -1) /* -1 for retrieving all matches, positive integer for limit number of matches */
                            /* Notice support for * and . wildcards */

{ key : 'Hello', values : {"id":1, "txt":"Hello World"} },
