Debug-output with tree of included files

[msiebuhr]

Make an option for printing some kind of tree showing the order of included files.

filea.cjson
  ` fileb.cjson
     ` fileb-1.cjson
     ` fileb-2.cjson
  ` filec.cjson
  ` ...

I haven't had the need for this when working with oconf. Could you add some motivation for this feature, and comment on wether or not you still feel this is needed?

I had the need after digging around the include-tree in one of the services that had a chain of configs that came from SCM, generated files, the packaging system and some chef-thingie.

If it still applies, there is a branch at https://github.com/One-com/node-oconf/tree/tree-resolver

It sounds sane enough to me. I'll probably not invest any time in it unfortunately. But I don't see any harm in landing it :-)
