precisionPhotonRecoSequence()

def PrecisionPhotonRecoSequences.precisionPhotonRecoSequence	(		flags,
			RoIs,
			name = None,
			ion = False
	)

With this function we will setup the sequence of offline EgammaAlgorithms so to make a photon for TrigEgamma 

Sequence of algorithms is the following:
  - egammaRecBuilder/TrigEgammaRecPhoton creates egammaObjects out of clusters and tracks. Here, at HLT photons we will only use clusters. 
  - photonSuperClusterBuilder algorithm will create superclusters out of the toposlusters and tracks in egammaRec under the photon hypothesis
      https://gitlab.cern.ch/atlas/athena/blob/master/Reconstruction/egamma/egammaAlgs/python/egammaSuperClusterBuilder.py#L26 
  - TopoEgammBuilder will create photons and electrons out of trakcs and SuperClusters. Here at HLT photons the aim is to ignore electrons and not use tracks at all.
