Flipping the Featured Header with the Banner

Looking at the inspect vs the raw theme code, the "header-featured-image" is below the "feature-slider" You guys have a massive amount of code there so I don't want to mess it up. I'm looking at flipping it. I noticed the inc folder contained "fullframe-featured-slider.php" and "fullframe-featured-header.php" with the corresponding code but the functions are written directly in so I don't want to break any functions for the client. Great work all the same
