/** \class IdealZPrism
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:
- eta, phi of axis
- Z location of front and back faces
- eta width and phi width of frontface
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.
