// THINGS TO DO YET: 

    // - Write the score function.
    // - Write the function for the end game condition (aka when the tree and the dino collidde)
    // - write the score function 
    // - Write the move_dino function 
    // - Write the game function that calls the move_dino ands the move_tree function
    // - Write the function for the max time the dino can stay in the air before it 
    //   starts falling down.
    // - Make the move dino function buitton-press-time sensitive
    // - correct the functions for two trees coming simullateneosuly so that they dont come
    //   together.
