   -This unit has been added in 2014.
   -Inspired a lot from "usearchtemplate"
   -Icon used for button to work with path is called "folder_wrench.png"
    and was taken from "http://www.famfamfam.com/lab/icons/silk/".
    It is already mentionned in the "about" section of the application
    that icons are coming from this site.
