description:
Added polygon to FacetNormal constructor.

Added domain() function to Expr.

Removed DefaultDim. This causes some trouble in AD,
but fixes some other stuff that was tricky.

Started implementation of precedence ordering.

Quick attempt at improving mark_duplications by skipping constants, needs review.
