Hello ROS Fans,

I have created a ROS package implementing behavior trees called pi_trees.  It is written in Python and is modeled after the most excellent executive_smach package (though without the visualizer).  The only documentation I have so far is a PDF which was copied out of a chapter from my latest ROS book mentioned earlier on the list.

The package consists of a standalone Python module and a ROS wrapper for connecting to ROS topics, services and actions.

Hopefully someone will find the package useful.  And if anyone can find problems with the code or a better way of doing things, I'd love to hear it.
