Major Description
currently the API defines the following to methods to access a Tree:
- Root#getTree(String path)
- Tree#getChild(String name)
the method on Root is current implemented by traversing the hierarchy (calling
Tree#getChild for all elements in the given path. that will not work in
situations where a parent is not accessible. similarly getChild only allows
to access a direct child.
i would suggest to redefine Tree#getChild to take a relative path or to
change the method to something like #getTree(String relativePath).
