Yakir, This looks pretty cool. In the past I have used SMACH[1] for my state machines. It works well but lacks event based state transitions. In particular I want to use service calls to change certain states. Is this something your library would support?

Currently we have implemented FSM's, HSM's and Behaviour trees. The documentation is still sparse, and not all the code is up, but we think it's already amazing. Here are some examples [3] We would be glad to collaborate with anyone interested (academy, research or commercial), welcome implementation of new models , comments and feedback.
