BehaviorTree.CPP

Noteworthy changes:

• A better way to include BTs from multiple files, either manually or using the <include> tag
• Adding a new Tree::sleep() method (experimental) to create event-driven trees.
• Example showing how to effectively use queues to do a "for-loop"
• Bug fixes

In this new release, there are many changes (including few that are breaking in API).

• New Switch ControlNode.
• Tree now provides two public methods: tickRoot() and haltTree()
• CoroAction (coroutines) now need Boost.
• most importantly, TreeNode::setStatus() is protected now!

The last change will be annoying for many people, but it is the only way to avoid nasty antipatterns.

There are few bugs fixed since version 2.2.0 (see CHANGELOG).

Someone code may break because the signature of the method registerBuilder had to change since the manifest was not created nor added to the manifest list.

See commit 6181d87cc1128485fb11fe7dd6e8c796348a38af for details.

This release includes a few changes that you can read in the CHANGELOG.rst.

The most notable is that SimpleActions, SimpleDecorators and SimpleConditions will not allow NodeParameters.
Check the tutorial T06 out to see a practical example of how this helps wrapping legacy code into a TreeNode.

With the latest change in CMake to support the installation of the library, it became apparent that the include needed some refactoring.

This will break the code of people using the previous version, sorry :(

Bear with me

It has been a long journey, but we are ready to announce the preliminary version of BehaviorTree.CPP
2.0.

Enjoy
