Updated scripts to include the TauRunnerAlg, allows the TauRecPi0EflowProcessor algorithm to be ran inbetween the two. Also moved write handles from TauPi0CreateROI and TauShotFinder to the TauProcessorAlg, required new functions and change to base class. Still need to finish adding tools to TauRunnerAlg
