>>>> Buffer saves data (using ECHO) <<<<
- Added inode to file and dir structs
- generate dynamic inode in lookup
- release and flush return only nil
- move o.publish() from flush to write() so that a new instance is not created
 and the buffer contains the new information.
 - the commit() and tag() update needed to be assigned to a newcommit and a newtag
 - Next steps: We still need to be able to rename and save from gedit
 - We can currently only change information by using the echo command
