0007 /** \class IdealZPrism
0008     
0009 Prism class used for HF volumes.  HF volumes are prisms with axes along the Z direction whose
0010 face shapes are set by 
0011 
0012 Required parameters for an ideal Z prism:
0013 
0014 - eta, phi of axis
0015 - Z location of front and back faces
0016 - eta width and phi width of frontface
0017 
0018 Total: 6 parameters
0019 
0020 Internally, the "point of reference" is the center (eta/phi) of the
0021 front face of the prism.  Therefore, the only internally stored
0022 parameters are eta and phi HALF-widths and the tower z thickness.
