//\class RPCGeometryESModule

Description: RPC GeometryESModule from DD & DD4hep
DD4hep part added to the original old file (DD version) made by M. Maggi (INFN Bari)
//
// Author:  Sergio Lo Meo (sergio.lo.meo@cern.ch) following what Ianna Osborne made for DTs (DD4hep migration)
//          Created:  Fri, 20 Sep 2019 
//          Modified: Fri, 29 May 2020, following what Sunanda Banerjee made in PR #29842 PR #29943 and Ianna Osborne in PR #29954
