Added clone capability.

[Added behavior tree library, subtree reference nodes and tests.](https://github.com/libgdx/gdx-ai/commit/19d4ed47ceb921147b22c077494f692b70ab0142) @implicit-invocation I created two distinct reference nodes instead of one with a lazy parameter, because they extend different classes: `Task` for...

@implicit-invocation ok, it makes sense. [Lazy and eager subtree inclusion is now implemented as a single decorator](https://github.com/libgdx/gdx-ai/commit/fcecadebc83b119ca159e6d6e43d5d392f1312d1). > And I still don't get why Metadata is static. You don't want...

@implicit-invocation Just pushed some javadoc, code clean up, and minor fixes. I'd like to release gdx-ai 1.4.0 on sunday (old releases were part of the libgdx project, so we have...

@implicit-invocation Ok thanks, no hurry. BTW, I'm thinking of renaming `Node` to `Task` which is the typical superclass name in all the API I've seen in the past. It makes...

TBH I don't see the problem. Usually the one who creates a tree (not necessarily the developer) is used to think in term of actions and conditions which are the...

Also, I want to to add '?' as a legal char for attribute names (see the 1st import below) and task aliases. This gives the user the opportunity to improve...

Just curious, what's your use case?
