Add support for printout(node_name: str)

[bestekov]

In an environment with a lot of different loggers configured (especially by 3rd party modules) it would be useful to be able to filter the tree to a particular starting root. The printout method has a node parameter, but it appears to require passing a node object rather than the name of the node.

Is there a way to either easily get a node object by name? Barring that would ideally like to be able to pass the name of the target logger to the printout method.

I think that the Standard Library call logging.getLogger() will let you pass a name, and return its node. Try it out and see whether it works!
