Class Description

 HGeomTube

 class for the GEANT shape TUBE

 The size of a TUBE is defined by 3 'points'.
   point 0:   origin of starting circle of the tube;
   point 1:   inner radius of starting circle,
              outer radius of starting circle;
              (z-component not used)
   point 2:   origin of ending circle of the tube;
 Warning: The x- and y-values of point 0 and 2 have to be the same!!!!
          A rotation has to be desribed via the rotation matrix.

 The intrinsic coordinate system of a TUBE, which sits in the CAVE and is
 not rotated, is identical with the laboratory system.

 constructor

 default destructor

 reads the 3 'points' decribed above from ascii file
 if the array of points is not existing in the volume it is created and
 the values are stored inside
 returns the number of points

 writes the 3 'points' decribed above to ascii file

 prints volume points to screen

 calculates the parameters needed to create the shape TUBE

 calculates the position of the center of the ROOT volume in the intrinsic
 coordinate system and stores it in the data element 'center'
 calls the function posInMother(...) to calculate the position of the
 volume in its mother
