The direction of a cluster's axis is not written out in CalorimeterClusterRecoCoG
Describe the solution you'd like
Define the cluster axis to be the unit direction of the eigenvector with the largest eignvalue of the moments matrix for the cluster. Include the x, y and z values of this vector in the shapeParameters
Describe alternatives you've considered
An alternative is to store these values as intrinsicTheta and intrinsicPhi, however these values are already being calculated as the direction from the origin to the centroid of the cluster.
