The members of this struct could also be changed to float SymMatrix3x3F SymMatrix2x2F Vector2F

There's an interplay between the CaloCluster members and those of LHCb::VertexBase and LHCb::Particle, which are still using doubles. This happens through CaloMomentum and CaloParticle, so it will be better to:

first clean up CaloMomentum and CaloParticle, and the duplicates between Calo and CaloFuture.
then move to float matrices in CaloClusters_v2.
