Init the Trie object and create root node.

        Creates an Trie object with a root node with the passed in
        max_edit_distance and match_threshold.

        Args:
            max_edit_distance(int): ?
            match_threshold(int): ?

        Notes:
            This never seems to get called with max_edit_distance or match_threshold
