The user may wish to turn off a listener by setting it to NULL.

It would be better if to separate the PreSolve and PostSolve from the
ContactListerner class. The two callbacks are some time-consuming when there 
are many
contacts and many games don't need them.

Tapir, did you run a profile? Is this affecting your frame-rate?

Hi, Erin,
I'm sorry, I thought it is so in theory but I just found it is wrong.
Seems b2Island.Report and b2Contact.Update cost much less time than 
b2Island.Solve ().
Whether or not the PreSolve and PostSolve are null is not important for the fps.

even
there are many contacts.
