From 2f2930f1ba0f1708fc4455c66173fd61188a3369 Mon Sep 17 00:00:00 2001
From: Christian Grothoff <christian@grothoff.org>
Date: Tue, 31 Oct 2017 14:02:54 +0100
Subject: major API refactoring, adding planchet generation and coin extraction
 APIs to the Taler crypto library, thereby simplifying code in withdraw,
 refresh, tipping, payback and testcases; slight API incompatibilities to
 previous versions are introduced
