Low: text field encoding

• There will be objects with fields (both in flat and tree)
• Two ways of encoding fields:
  • positional
    • line length limit
    • fixed fields
    • optional fields
    • vararg
    • Special case: column based!
  • named fields
    • order of fields
    • optional fields & vararg
• long term: named!
