Huber Cost Function.
Loss function as described by Huber See http://en.wikipedia.org/wiki/Huber_loss_function
If e^(1/2) < d rho(e) = e
else
1/2 2
rho(e) = 2 d e - d

compute the scaling factor for a error: The error is e^T Omega e The output rho is rho[0]: The actual scaled error value rho[1]: First derivative of the scaling function rho[2]: Second derivative of the scaling function
Implements g2o::RobustKernel.

set the window size of the error. A squared error above delta^2 is considered as outlier in the data.
