Although this object could pretty much qualify as done, I'm going to post it here as a beta for now to make sure the bugs are worked out. Anyways, onto what this plugin does.
What it does:
This is essentially a far more advanced version of my Orbiter behavior. BUT... instead of merely rotating an object around another object in a completely predictable/stable orbit, this acts more like a gravity well. You can set an object to act as a satellite, an attractor, or both, where every object could have it's own pull on the others and orbit the others as well.
Also, you can apply forces to the objects(in a way similar to the physics behavior) to make them move in certain ways. You can use the movement actions to make a space ship movement, for example.

Full documentation will come when I release the completed version. If you have any specific questions about what something does, go ahead and ask and I'll explain. Be sure to let me know about any bugs you find, and have fun with it.
By the way, just thought I'd mention the speed impact of this object. I would keep the amount of objects simultaneously orbiting and attracting to around 100, depending on what type of processor you have. Although it's good to point out that this object is 5-10 times faster than doing the same thing through events.
