Add Spring to Motion Study Example (VB.NET)

This example shows how to add a spring to a motion study.

'---------------------------------------------------------------------------
' Preconditions:  
' 1. Open install_dir\samples\tutorial\api\wrench.sldasm.
' 2. The MotionManager tab is visible. If it is not visible,
'    click View > MotionManager.
' 3. Right-click the project, select Add Reference, click Browse, and
'    select install_dir\api\redist\CLR2\SolidWorks.Interop.swmotionstudy.dll.
'
' Postconditions: A spring feature is added between the grips of the wrench.
'
' NOTE: Do not save the model after running the macro.
