Detailed Description

Concrete class derived class from pure virtual eflowAbstractCellList.

This stores information about the calorimeter cells - the main data type is a map between an eflowCellPosition and a pair linking the CaloCell pointer and the index of its xAOD::CaloCluster in the calorimeter cluster container. A DR2 function is provided to calculate the distance between an eflowCellPosition and the track impact point in a given calorimeter layer (eflowCellList also stores a list of track eta,phi impact points for each calorimeter later).
