Initial implementation of the DCAL Geometry (work done by Mengliang WANG for his service task). 3 versions have been implemented: - EMCAL_COMPLETE12SMV1_DCAL: 12 EMCAL SM + 6 DCAL SM - EMCAL_COMPLETE12SMV1_DCAL_DEV: 12 EMCAL SM shifted and 10 DCAL SM (this is a possible future DCAL geometry) - EMCAL_COMPLETE12SMV1_DCAL_8SM: 12 EMCAL SM and 8 DCAL SM (the current DCAL geometry)
