Is auto diff working now?

[amberwood31]

May I know whether the auto differentiation feature working now? The ceres dependency seems to indicate that. But I did some simple test, it seems that numerical jacobian is still the default behavior if I don't define the analytical jacobians.

If the auto differentiation feature is already working, can you kindly advise how to enable it?

An example using ceres autodiff:

g2o/examples/bal/bal_example.cpp

Not sure if this is what you need.

Thanks! I also found an example in the unit_test folder. Will give it a try.
