[tongtybj]

What is this

Create a kalman filter library that is implemented a single header file

Details

• Time synchronization: consider the timestamp of each sensor value: https://github.com/jsk-ros-pkg/jsk_control/compare/master...tongtybj:jsk_control:develop/kalman_filter?expand=1#diff-b13193d01b631f1b777e116374d3212982de661cb38840ef166e7158b4c96685R177
• Write the core of kalman filter in a single header file: jsk_kalman_filter/include/jsk_kalman_filter/kf_base_plugin.h
• Write a derived class that estimates pos/vel with acc input: jsk_kalman_filter/include/jsk_kalman_filter/kf_pos_vel_acc_plugin.h

TODO

• [ ] add test/sample codes
• [ ] add usage documentation
