In Orbit 2

I had some complaints about the accuracy of my last 'Orbit' Applet, so I decided to go for a more technically responsible version. However, it should be noted that this applet is very crappy. I have something much better in the works.

It is funny to watch as certain particles get continually 'flushed' down the virtual 1/r² gravity well. Others are flung off at very high velocities as they get way too close to the sun. My original version featured a not-too-shabby n-particle simulations (where they were all attracted to each other). It's much cooler to do a simulation with a super-heavy particle and neglect the interactions of the rest of them, though.
