Get BCurve Spline Points Example (C#)

This example shows how to get B-spline parameter data (knots, control points, etc.) for a selected spline
or curve.  

//---------------------------------------------------------------------------
// Preconditions:
// 1. Open install_dir\samples\tutorial\molds\telephone.sldprt.
// 2. Select a curve.
// 3. Open the Immediate Window.
//
// Postconditions: Examine the Immediate window.
