Add and Delete Materials from Specific Display States (VB.NET)

This example shows how to add material to and delete material from specific display states.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Specified model exists.
' 2. Specified material exists.
' 3. Open an Immediate window.
'
' Postconditions:
' 1. Display State 2 and Display 3 are created
'    for the active configuration.
' 2. Specified material is applied to all display states
'    of the active configuration.
' 3. Specified material is deleted from all display states
'    of the active configuration.
