Add and Remove Files from Pack and Go Example (C#)

This example shows how to add SOLIDWORKS, render reference, and non-SOLIDWORKS files to Pack and Go. This example also shows how to remove a non-SOLIDWORKS file from Pack and Go.

// Preconditions:
// 1. Verify that the specified assembly exists.
// 2. Create c:\PackAndGo.
// 3. Open the Immediate window.
// Postconditions:
// 1. Gets the names of SOLIDWORKS, render reference, and
//    non-SOLIDWORKS files for Pack and Go.
// 2. Gets the the name of non-SOLIDWORKS file to remove.
// 3. Packs up SOLIDWORKS, render reference, and
//    non-SOLIDWORKS files and copies them to c:\PackAndGo.
// 4. Examine c:\PackAndGo and the Immediate window.
