[Timber] Compiler milestone

[Viktor Leijon]

Hej.

Det första du ska få är min parser-diff:
pub98-187:~/tmp/timber/timber leijon$ darcs diff Parser.y
192c192
<         : selvar exp                          { Field $1  $2 }
---
 >         : selvar '=' exp                              { Field $1   
$3 }

Jag återkommer med testfall som jag tycker borde fungera.
