/**
 * The {@link ListResultTransformer} simplifies the way
 * we can use a ResultTransformer by defining a default implementation for the
 * {@link ResultTransformer#transformList(List)} method.
 * 
 * This way, the {@link ListResultTransformer} can be used
 * as a functional interface.
 * 
 * For more details about how to use it, check out this article on vladmihalcea.com.
