This directory contains the Pybind11 binding code used by the moveit_py package.
The root of this directory contains the actual module definitions (e.g. core.cpp defines the moveit_py.core module).
The structure of subfolders in this directory reflects that of the MoveIt 2 C++ codebase. Within each subfolder you will find the actual binding code that each module leverages.
For instance, to see how the PlanningScene object is being binded you can refer to the source files in ./moveit_core/planning_scene/.
