From 130d73eaa90fb40dd7d941b6a706036477ea8cdd Mon Sep 17 00:00:00 2001
From: Dennis Schafroth <dennis@indexdata.com>
Date: Thu, 15 Jul 2010 14:30:30 +0200
Subject: [PATCH] Support for printing of facets.

- Rename display_term to display_term_info (as it is such a object it prints)
- Extract display_term from display_queryExpression to display a term
- Fully implement the display facet using new facet helpers.
