/**
 * Lombok is smart enough to translate any annotation named <code>@NonNull</code> or <code>@NotNull</code> in any casing and
 * with any package name to the return type of generated getters and the parameter of generated setters and constructors,
 * as well as generate the appropriate null checks in the setter and constructor.
 * 
 * You can use this annotation for the purpose, though you can also use JSR305's annotation, findbugs's, pmd's, or IDEA's, or just
 * about anyone elses. As long as it is named <code>@NonNull</code> or <code>@NotNull</code>.
