Testimonial Carousel

NOTES: If we ask the user how many testimonials to show on the screen at any time, (dropdown choice) we can then put the proper wrapper column class on the cards. For example, if the user only wants to show one card at a time, we need to col-md-12 class. This would be ideal if the user places the testimonial carousel in a smaller, side column.

If they plan to show the testimonials 2 or 3 up, (3 is max) we can use the col-md-6, and col-md-4 classes respectively. 

I'm not sure yet how to set the background color of the 'cards' (the parent) if the user chooses the template with the circle photo centered below the quote. This template needs to have #eee background color on the parent. In this proto example, the css is inline.

Usage note: I wouldn't recommend using different templates within the same carousel. Although the flex properties on the cards will make the all the same height, there may be too much white space on testimonial templates that don't use images.
