The Boggle game.

Serialize and deserialize a tree.

Given a tree - not necessarily a binary tree - the serialize method should create a string for the tree. The deserialize method should be able to reproduce the same tree using the string derived from the serialize method.

Basically, serialize() takes in a tree and returns a string, deserialize() takes in a string and returns the tree.
