Detailed Description

The SiLayerBuilderCond parses the senstive detector elments and orders them onto a Layer surface.

It also uses the SiNumerology to construct the BinUtility and then orders the representing detector surfaces on the layers.

It performs an automated detector if an equidistant or non-equidistant binning is to be used for the barrel case.
