dust_style_filetree_display

This crate contains the display components from dust. They have been ripped off, almost verbatim, from there! I have removed some of the things that aren't useful for a library user but this is a very quick and rough crude rip-out job — I haven't documented anything or finished taking effort to clean it up.

The dust style is nice and could be useful in other projects, that want to be look the same as dust (e.g. because they want to be familiar to dust users, in order to display size tree information whilst not displaying exactly what is on the filesystem).

The dust project is licensed under the Apache 2.0 licence, so this crate will do the same.
