Expand, Collapse, and Dissolve Subassembly in a BOM Table Example (C#)

//-----------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\assemblyvisualize\food_processor.sldasm.
// 2. Select File > Make Drawing from Assembly.
// 3. Click OK.
// 4. Drag one or more views onto the drawing.
// 5. Ensure that the specified template exists.
//
// Postconditions:
// 1. Inserts an indented BOM table in the drawing.
// 2. Collapses the blade shaft subassembly. Press F5 to continue.
// 3. Expands the blade shaft subassembly. Press F5 to continue.
// 4. Dissolves the blade shaft subassembly. Press F5 to restore the blade
//    shaft subassembly.
//
// NOTE: Because this document is used by a SOLIDWORKS
// online tutorial, do not save any changes when
