0008
0009   Oblique prism class used for HCAL  (HB, HE, HO) volumes.
0010
0011   Required parameters for an ideal oblique prism:
0012
0013   - eta, phi of axis
0014   - radial distance (along axis) to front and back faces
0015   - single bit - faces parallel or perpendicular to z-axis
0016   - eta width and phi width of faces (same for front/back)
0017
0018   Total: 6+1 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 widths, the axis tower thickness, and the
0023   parallel/perpendicular setting.  The parallel/perpendicular setting
0024   is encoded in the sign of the thickness.  (positive = parallel to
0025   z-axis, negative = perpendicular)
