Description

We already have a tool for converting edit logs to and from binary and xml. The next logical step it to create an `oiv` (offline image viewer) that will allow users to manipulate the FS Image.

When outputting to text, it might make sense to have two output formats - 1) an XML that is easier to convert back to binary and 2) something that looks like the output from `tree` command.
