Insert Magnetic Line Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\Assem20.slddrw.
// 2. Open the Immediate window.
//
// Postconditions: At each System.Diagnostics.Debugger.Break() statement,
// observe the Immediate window and drawing, then press F5:
// 1. Inserts a magnetic line.
// 2. Attaches two notes to the magnetic line.
// 3. Detaches one note from the magnetic line.
//
// NOTE: Because the drawing is used elsewhere, do not save changes.
