_____________________________________________________________________________
 TGeoHalfSpace - A half-space defined by:
            p[3] - an arbitrary point on the plane
            n[3] - normal at the plane in point P
    A half-space is not really a shape, because it is infinite. The normal
    points "outside" the half-space
_____________________________________________________________________________

 Dummy constructor

 Constructor with name, point on the plane and normal

 Default constructor specifying minimum and maximum radius

 destructor

 test if point is inside the half-space

 compute distance from inside point to the plane

 compute distance from inside point to the plane

 print shape parameters

 Save a primitive as a C++ statement(s) on output stream "out".

 Set half-space parameters as stored in an array.
