Add Spring to Motion Study Example (VB.NET)

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

' Preconditions:  
' 1. Open public_documents\samples\tutorial\api\wrench.sldasm.
' 2. Verify that 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.
' 4. Open the Immediate window.
' Postconditions:
' 1 Adds a spring feature between the grips of the wrench.
' 2. Examine the Immediate window.
' NOTE: Because the assembly is used elsewhere, do not save changes.
