Relative paths

[preethampaul]

While using cd, ls or other file handling commands, the relative paths do not work well. The parse_drive_paths function in drive_util works well, problem is with the commented snippets in gd.py.

if drive_path.startswith('/'):
      drive_path = '~/' + drive_path[1:]
      
if CURR_HOME_DIR in drive_path:
      drive_path = drive_path.split(CURR_HOME_DIR)[-1]
 
if drive_path=='/':
     drive_path = '~'
