New Test - * size for the portal * re-size graphics * re-size the .gifs * change outputs * add pexit, pfexit and M2 to output * update EngineSimU * update application * fix translation for viewer * correct gross thrust calculation * change view box for title add CPR to output fix bug in turbofan weight calculation Old Test - clean up TJB 5 Feb 13 */ import java.awt.*;
