class TEveBoxSet: public TEveDigitSet

 Collection of 3D primitives (fixed-size boxes, boxes of different
 sizes, or arbitrary sexto-epipeds, cones); each primitive can be assigned
 a signal value and a TRef.

 A collection of 3D-markers. The way how they are defined depends
 on the fBoxType data-member.
   kBT_FreeBox         arbitrary box: specify 8*(x,y,z) box corners
   kBT_AABox           axis-aligned box: specify (x,y,z) and (w, h, d)
   kBT_AABoxFixedDim   axis-aligned box w/ fixed dimensions: specify (x,y,z)
                       also set fDefWidth, fDefHeight and fDefDepth
   kBT_Cone            cone defined with position, axis-vector and radius
   EllipticCone        conew with elliptic base (specify another radius and angle in deg)

 Each primitive can be assigned:
 a) Color or signal value. Thresholds and signal-to-color mapping
    can then be set dynamically via the TEveRGBAPalette class.
 b) External TObject* (stored as TRef).
