// An "Athena algorithm" is something which gets scheduled and controlled
// by the framework. In its simplest definition it is something which
//  - gets called for each event 
//  - can get anything it wants out of the Transient Event Store"
//  - can put anything it makes into the store.
//
// It must inherit from the  Algorithm base class
