Detailed Description

A cell of the hadronic endcap calorimeter readout geometry.

This class represents a single HEC Cell. A cell spans multiple blocks and has different boundaries at each block. For access to the HEC Cells, use the HECDetector Region class.

Use the HEC Cells through HEC Cell Links please!!! This will free the memory used by the cell when the last link to the cell disappears.
