1. 2 game object id's are set as local strings for horizontal and vertical examples.

2. bee_flip() function takes in the go's id then an if statement is used to determine go's
    position and sets horizontal or vertical flip to sprite accordingly. Then go.animate is
    used and a callback to bee_flip() occurs at the end of the animation.

3. In the initialize function we call bee_flip() for both horizontal and vertical bee 
    game objects.
