* Updated with a short demo on sample AV LIDAR scans
* Added README with a short summary of the code
* Working state of Multiple object stable tracking using Lidar scans with an extended Kalman Filter (rosrun kf_tracker tracker). A naive tracker is implemented in main_naive.cpp for comparison (rosrun kf_tracker naive_tracker).
* v2. Unsupervised clustering is incorporated into the same node (tracker).
* v1. Object ID/data association works. In this version PCL based unsupervised clustering is done separately.
