From 76b9348d4ba4c856d888b32f31f1fa7d80e35cbf Mon Sep 17 00:00:00 2001
From: Adrian Kummerlaender

Subject: Added recursive traversion of all folders in each level * enables
 representing the result folder structure in the source ** e.g. the "page.xsl"
 transformation is located in "source/pages" and the result is therefore
 written to "target/pages" ** this enables simplification of target metadata
 as it is now automatically relative to the level * modified page template
 accordingly
