iOS: Implement layout constraints to put the UIStackView containing the columns below the row's image and text label and attempt MULTI mode. Need to figure out how to add the stack's extra height to the cell. Multi mode is implemented with UIButtons and I am getting a weird selector sent to the buttons when in Multi mode.
