From e1804b3d0ef3be3db8be169043c6eae8a98bbc86 Mon Sep 17 00:00:00 2001
From: rsiddharth <rsiddharth@ninthfloor.org>
Date: Wed, 31 Oct 2012 23:32:29 +0530
Subject: added:   status/   status/DirectoryInfo.java (record the directory
 'level' at which                              scruf is parsing with respect
 to 'root' 							 directory.)

modified:
  Scruf.java (added a line to start the directory level count at zero)
  conversion/ConvertDirectory.java (DirectoryInfo.level used to take
  								   	count of directory 'leve')

  conversion/ConvertFile.java (lines related to 'footer' things were removed)
  io/PresentFile.java ( 'footer' & 'backButton' field removed)
  parsers/BackButton.java (back button placement happens in the parse
  						   method itself, instead of doing it in Header.java)
  						  (back button is not placed, if the present
						   directory is root directory)
  parsers/Footer.java (footer placement happens in the parse
  					   method itself, instead of doing it in Header.java)
  parsers/Header.java (back button placement & footer placement removed.)
