From 314a41be6b39b6c5967d79555dbf018dbc7eb5f6 Mon Sep 17 00:00:00 2001
From: Tyge Løvset <tylo@norceresearch.no>
Date: Sun, 22 May 2022 20:45:31 +0200
Subject: Rewrote cbits to make it dual: fixed-sized or dynamically sized by
 adding optional i_len template parameter. Renamed cbits_set_values() to
 cbits_set_pattern(). Added example bits2.c
