Designing doument for Tetris

We upload the designing document for the tetris game is a little vague for my taste in the eventHandler methods because we really don't know how it will be implemented to the block or object that will call this methods so we made like a guess and put the description, hope the next week could like make clearer the design as the implementation, I'm a little exciting about the next weeks how it will result the tetris game and I hope it won't be a mess or a complete caos when we decide to join all the modules.
