Insert New Instance of Virtual Component (C#)

//-----------------------------------------------------
// Preconditions: None
//
// Postconditions:
// 1. An assembly document is created.
// 2. A virtual part is inserted in the assembly document.
// 3. A new instance of the virtual part is inserted
//    in the assembly document.
// 4. Examine the FeatureManager design tree to
//    verify steps 2 and 3.
// 5. Close the assembly document without saving the modified
//    documents.
