Some notes

• Object movements are independent of each other, so 2 objects can even be on top of each other.

• You can change the # of objects in the config file. However, the trace file is not overwritten/regenerated if it already exists. If you change the # of objects in the config file, but use a trace file that was generated with a different # of objects, some objects might not have traces, which can cause an exception. You may want to delete the trace manually, when changing the # of objects. Also, you can specify the following attribute: overwrite="yes" , for any tag in the xml, where there is also a filename="" attribute; this will cause the trace to be overwritten/regenerated every time you rerun the simulator.
