Detailed Description

The JetInputKey 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 JetInputKey now inherits from JEKey (which is essentially the original JetElementKey, & itself inherits from KeyUtilities)
