Double click green flag to start simulation. Added customisations for planets and the system. Click the planet to customise its variables. If it shoots out of the screen, you can press the number of the planet respectively to get its customising menu. Then you can get it back into the screen. Also added play/pause simulation buttons. This is a simulation of some solar system. It uses simple Newtonian laws to describe how the planets move and interact. Don't consider this debugged; loads of glitches to be fixed. Use turbo mode (shift-click green flag) for faster speed of the planetary movement.
