  This definition represents an individual segment along the IfcAlignment2DVertical, being defined in the distance-along/z coordinate space.
  The vertical alignment is defined by segments that connects end-to-start. 
  The vertical alignment curve geometry is defined in a plane with x = distance along horizontal, the y = height (or elevation). 
  The transition at the segment connection is not enforced to be tangential, 
  if the “tangential continuity” flag is set to false, otherwise a tangential continuity shall be preserved.
  
  The following vertical segment types are defined:
  * line segment - IfcAlignment2DVerSegLine
  * circular arc segment - IfcAlignment2DVerSegCircularArc
  * parabolic arc segment - IfcAlignment2DVerSegParabolicArc which can describe symmetric and asymmetric parabolas
