Detailed Description

The JetElementKey object provides the key for each JetElement depending on its eta,phi coords (JetElementKey differs from JetInputKey in that ElementKey has 0.4 FCAL granularity, while InputKey has 0.2 FCAL granularity).

As 2 implementations are required for the Jet and Energy triggers, differing only in the FCAL granularity, we solve this problem by inheritance. Thus JetElementKey now inherits from JetElementKeyBase (which is essentially the original JetElementKey, & itself inherits from KeyUtilities).

The key is an integer number that uniquely identifies each tower, and is needed by the STL map container: the map holds trigger towers and we retrieve them using their keys.
