Do you have the scripts to collect the demos on the real robot?

There was a breaking API change in v1.8.0 [changelog](https://github.com/OctoMap/octomap/blob/devel/octomap/CHANGELOG.txt#L45). Any help with how to modify the current files. In particular file `octomap_ig_tree_node.hpp ` function `inline IgTreeNode* getChild(unsigned int i)`

Can you please provide example and test script on how to run FIF with ros. i.e compute FIF on a published ros topic.

Do you have examples on how to train the policy from real demonstration and on real robot?
