Re: Behaviour Tree PropClass

Not sure what is the problem here, it may be due to the fact that you
declare two different SCF interface in "behaviourtree.csplugin",
although they reference the same implementation object
(celPfBehaviourTree).

Something that I didn't notice before is that you are actually
implementing the BT propclass within the "plugins/tools/behaviourtree"
directory, while it would have been much cleaner to put it with the
other propclasses in "plugins/propclass".

Similarly, the header file should be put in "include/proclass", and all
other BT code in "plugins/tools/behaviourtree" should remain as they
were prior your propclass addition. Your propclass would simply be a
wrapper over the tools implemented in "plugins/tools/behaviourtree", no
need to change anything on that side.

Doing so, your BT propclass would also have the exact same file
structure than every other propclass, and it would be much easier to
find out what's problematic here.
