From 29a9fb20b4c8414f2590886e43ae86794a53db89 Mon Sep 17 00:00:00 2001
From: Adrian Kummerländer

Subject: Implemented support for modifying external function base path * one
 expects a read-file function to work relative to the directory the
 transformation is located and not to the executable's location ** from the
 perspective of the user the transformation is the application, not the actual
 executable * removed PlattformGuard struct from TransformerGuard (now
 TransformerFacade) * TransformerFacade is instatiated with the appropriate
 relative working path ** i.e. it will have to be instantiated for every
 directory containing one or more transformations
