implementing the traverseLayers function from xtools stdlib.js

I am trying to figure how to make a script which can search for a specific layer name in the layer palette, layer group and nested layer groups.

I came across the xtools traverse layer function in the sdlib.js which might do the job. How to  implement this function was not clear to me.

I would like to ask help from the scripting community to figure out how apply to this function to a script. I am not a programer and have basic javascript knowledge.

thanks in advance
