/**
 Debugging client for the Piece class.
 The JPieceTest component draws all the rotations of a tetris piece.
 JPieceTest.main()  creates a frame  with one JPieceTest for each
 of the 7 standard tetris pieces.
 
 This is the starter file version -- 
 The outer shell is done. You need to complete paintComponent()
 and drawPiece().
