From 1d4472c3e6bad242c04ab5925ac12b3053ece323 Mon Sep 17 00:00:00 2001
From: Dan Gudmundsson <dgud@erlang.org>
Date: Wed, 30 Mar 2011 12:50:03 +0200
Subject: Add timer:tc/1 which measures elapsed time for a fun/0

Also removes the 'catch' from timer:tc functions which masked errors
in measuring code.
