void Tetrahedron (void )

Default constructor 
Creates an empty Tetrahedron .

void Tetrahedron (const Point& p, const real diameter_of_triangle, [real angle_x = 0, [real angle_y = 0, [real angle_z = 0]]])  Constructor 
Creates a Tetrahedron with its center at the origin.
The faces have enclosing circles of diameter
diameter_of_triangle. If any of angle_x, angle_y, or
angle_z is nonzero, the Tetrahedron is rotated by the
amounts specified around the corresponding axes. Finally, if p is
not the origin, the Tetrahedron is shifted such that
center comes to lie at p.
The center of a Tetrahedron t(origin, 3); t.draw();
Point P(1, 0, 1); Tetrahedron t(P, 2.75, 30, 32.5, 20); t.draw();

void set (const Point& p, const real diameter_of_triangle, [real angle_x = 0, [real angle_y = 0, [real angle_z = 0]]])  Setting function 
Corresponds to the constructor above.
