//GameScreen class is an extension of the base Nokia Library Created by Craig Evans
// This extension adds functionality relevant to 'Fall Down Game'.
// drawPlatform, drawBall, drawScore etc....
// # of platforms defined and can be altered/
// updates platforms at speed proportional to speedOfPlatforms_
// manages location and state of all platforms + player ball

//ISSUES:
//  text is written in wrong plane. Easy fix if I had access to private members of N5110...could just edit lib...
//      could also override current fontarray... look into this later.
