Relative path 0.1.0 for Nuke (nuke script)

Helps to use relative path in any node like read/write/geo and so on

Installation:
just place this tcl-file anywhere you like in plugins dir.

Usage:
use string like [up 1]/Render or [up 2]/Src in node file path.
[up 1]/Render is equal to ../Render
[up 2]/Src is equal to ../../Src

The simplest way to understand how it works - place sample string to a Text node and see the result in Viewport. You have to save your script before cause it treats the path taken from root.name knob.

Working under Windows. Linux and MacOs not tested.
