     Remove a directory and all of its contents.

     The results of executing File.delete() on a File object
     that represents a directory seems to be platform
     dependent. This method removes the directory
     and all of its contents.

     @return true if the complete directory was removed, false if it could not be.
     If false is returned then some of the files in the directory may have been removed.
