 NRBLINE: Construct a straight line.
 
 Calling Sequence:
 
   crv = nrbline()
   crv = nrbline(p1,p2)
 
 INPUT:
 
 p1		: 2D or 3D cartesian coordinate of the start point.
 
 p2            : 2D or 3D cartesian coordinate of the end point.

 OUTPUT:
 
 crv		: NURBS curve for a straight line.
 
 Description:
 
   Constructs NURBS data structure for a straight line. If no rhs 
   coordinates are included the function returns a unit straight
   line along the x-axis.
