DD4hep ---- Release Notes
=================================
+2015-08-12 N.Nikiforou
+-----------------------
+ - DDCore/XML: Added new helper functions to Layering engine:
+ - double absorberThicknessInLayer(XML::Element e) :
+ returns total absorber thickness in given layer
+ - void sensitivePositionsInLayer(XML::Element e, std::vector<double>& sens_pos) :
+ provides positions of sensitive slices within a layer with respect to the
+ center of the layer
+
