/*
This script is useful if you wanted to get a list of the files and folders within a directory on your web site.

EG: Lets say you wanted to monitor your theme folder in wordpress. With this script you can generate a list of
    all the files and folders and check for any changes.
    
    You could extend this script to exclude certain folders or file names or file types.
