 **
 **   Description:  - Algorithm-derived class to run after the Steering
 **                 - Finds the list of defined signatures at initialization
 **                 - For each event:
 **                   * Creates a TriggerDecision object
 **                   * Fills it with the outcome of each defined signature
 **                   * Stores it in StoreGate to be written to ESD/AOD
