Expand Component in Specified FeatureManager Design Tree Pane Example (C#)

This example shows how to expand a component in the specified FeatureManager design tree pane.

//-------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\pdmworks\speaker.sldasm.
// 2. Select speaker_frame<1> in the FeatureManager design
//    tree.
//
// Postconditions:
// 1. Expands the selected component in the top pane of the 
//    FeatureManager design tree.
// 2. Examine the top pane of the FeatureManager design tree
//    and the Immediate window.
//
// NOTE: Because this assembly is used elsewhere, do not
