   * As long as your custom cell classes are laid out in Interface Builder and
   * have Autolayout constraints to the top and bottom edges of the content view,
   * the size of the cell can be computed based on how tall it needs to be.
   *
   * USE AT YOUR OWN RISK. This causes a noticable performance hit on a table of
   * only about 15 cells. It might work OK on tables with only a few cells, but
   * be sure to test it for your actual use case. I'm only sharing this on gist
   * because I found it interesting.
