Request for CKF.

[ljgdasfhk]

Hello.
Do you have any plans to implement 3-CKF or 5-CKF.
For example as in
https://github.com/irvingzhang/KalmanFiltering
https://github.com/haransll/Lidar_Radar_Tracking_using_CKF
https://github.com/korken89/Comparison-of-UKF-CKF-EKF
https://github.com/Piyush3dB/ckf-matlab

A CKF implementation would be a great addition and is certainly somewhere on the todo list, but not with a high priority right now. A contribution of a high-quality CKF implementation would be greatly appreciated as well.
