The `ParentChild` tests have been generalized to test all `PrintAst` by factoring out `PrintAstNode` into a separate file. The `child.ql` and `parent.ql` tests have been removed as they are subsumed by `PrintAst.ql`. Also, a new `no_parent_child_loops` is added to detect back edges to a root node (back edges to a non-root node are already detected by `no_double_parents.ql`).
