Detailed Description

 @brief Description of a region of homogenous granularity in the 
 electromagnetic endcap calorimeter

This class combines a description of the cell
granularity with a physical volume to create a description of an EMEC region positioned within ATLAS. It provides access to the EMEC Cells.
