changed nose cone and transition shoulder diameters to be consistent with body tube inner diameter; changed parachute characteristics to reduce decent to appropriate rate; moved centering forward and middle centering rings to ends of fins; changed fin tabs to be consistent with 15.03; rotated launch lugs so that rod is not going through fins.
Separate swing application code from core code. Moved a bunch of sources
and libraries around. Created new eclipse project.
Further refinements to make it build.
Update gitignore.
