This example shows how to add a spotlight to a model and get its light
feature.
//-------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified assembly document exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified assembly document.
// 2. Adds a spotlight.
// 3. Gets the spotlight's feature and prints its ID to
// the Immediate window.
// 4. Examine the Immediate window, FeatureManager design tree, and
// graphics area.
//
// NOTE: Because this assembly document is used elsewhere, do not save changes.
