level asset highlighting

Right now the scene is just 2 rockets. The other rocket needs to be a sailboat and I will add that in later tonight. This is the opening scene the player will always start in. When the player moves his or her head, depending on which object they are staring at, that object will highlight. When the player pushes a button on the spirometer the highlighted object will be selected and start that corresponding game. Right now the scene is very basic but I will talk to andrew and see if we want to add grass and trees or something or leave it as-is
