Traverse Assembly at Component and Feature Levels Using Recursion Example (VB.NET)

This example shows how to traverse an assembly at the component and feature levels using recursion.

'-------------------------------------------
' Preconditions: Open an assembly document containing nested subassemblies.
'
' Postconditions: 
' 1. Output of the assembly traversal is shown in the Output Window.
' 2. The elapsed time to traverse the assembly is also shown
'    in the Immediate Window.
