Prism class used for HF volumes. HF volumes are prisms with axes along the Z direction whose face shapes are set by
Required parameters for an ideal Z prism:
Total: 6 parameters
Internally, the "point of reference" is the center (eta/phi) of the front face of the prism. Therefore, the only internally stored parameters are eta and phi HALF-widths and the tower z thickness.
