Applying color scheme

Apply a unified color scheme to an entire presentation:

// Create additional slides to demonstrate theme application
let slide1 = presentation.GetSlideByIndex(0);
let slide2 = Api.CreateSlide();
let slide3 = Api.CreateSlide();
presentation.AddSlide(slide2);
presentation.AddSlide(slide3);

// Get the master slide for theme creation
let master = presentation.GetMaster(0);
