From 334efe3383c436d61a8e5dd95b923cb0d5db9652 Mon Sep 17 00:00:00 2001
From: Adrian Kummerländer
Date: Sat, 19 Apr 2014 15:01:33 +0200
Subject: Further code style fixes * .. in the face of the planned development
 of usable external functions using the current proof-of-concept coding *
 replaced usage of std::shared_ptr in FunctionReadXmlFile class with explicit
 implementation of default and copy constructor * separated implementation and
 interfaces
