// This is an example of how more than 22 fields could be mapped with Slick 3.3.1 (other versions may work as well?).
//
// The general idea is pretty simple:
// 1. define a case class made of nested case classes.
// 2. define a projection made of nested projections.
//
// In addition, you can just get rid of noisy usages of ``GetResult`` generated by the Slick Code Generator.
// Just get rid of that, since usage of ``mapTo[T]`` makes definition of projections clean and hygienic.
