b2ManifoldPoint - position of contact

[GoogleCodeExporter]

b2ManifoldPoint stores its local position oddly. As this is now user
accessible, I think an method should be added for calculating an estimate
for the point of contact.
I.e. for polygons, return the point as is, and for circles, offset by
radius * normal.
It might also be helpful to provide a method to extract information from
the contact id. Say, the nearest edge involved on both shapes, treating
circles as having only one edge.

Have you seen b2WorldManifold and b2GetPointStates?

BTW, I might go back to the old style of manifold. I haven't decided yet.

Fair enough.

I added documentation for b2WorldManifold and b2GetPointStates.
