This is a command line tool to list all trees in a root file.

The behaviour should be similar to that of `root_numpy.list_trees`. That is,

trees in subdirectories in a file are listed.

This should shorten a user's lookups traversing subdirectories.

The tool is intended to ease usage of other command line programs that read

trees from root files, such as DooSelection tools or the

[tmva-branch-adder](https://github.com/pseyfert/tmva-branch-adder). It can be

used for tab completion functions.

printout looks like:

```

pseyfert@robusta ~/coding/tmva-branch-adder > root-ls-tree /afs/cern.ch/user/p/pseyfert/DTT.root

EventTuple/EventTuple	B02DD/DecayTree	GetIntegratedLuminosity/LumiTuple

```

# TODO:

 - for the intended use case of tab completions, low latency is key, so a

   closer look at performance should be taken at some point.

 - possibly an argument to prepend path names to the printout in a root

   standard format (`rootls` accepts `.root:/`) So for

   some interfaces having filename and tree path together might be more

   convenient:

```

pseyfert@robusta ~/coding/tmva-branch-adder > root-ls-tree -f /afs/cern.ch/user/p/pseyfert/DTT.root

/afs/cern.ch/user/p/pseyfert/DTT.root:EventTuple/EventTuple

/afs/cern.ch/user/p/pseyfert/DTT.root:B02DD/DecayTree

/afs/cern.ch/user/p/pseyfert/DTT.root:GetIntegratedLuminosity/LumiTuple

```
